Extending the Grading of Recommendations Assessment, Development and Evaluation (GRADE) in Traditional Chinese Medicine (TCM): The GRADE-TCM. PHYTOMEDICINE : INTERNATIONAL JOURNAL OF PHYTOTHERAPY AND PHYTOPHARMACOLOGY 2024; 127:155487. [PMID: 38490078 DOI: 10.1016/j.phymed.2024.155487] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 09/19/2023] [Revised: 01/29/2024] [Accepted: 02/25/2024] [Indexed: 03/17/2024]
Abstract
AIM To extend and form the "Grading of Recommendations Assessment, Development and Evaluation in Traditional Chinese Medicine" (GRADE-TCM). METHODS Methodologies were systematically reviewed and analyzed concerning evidence-based TCM guidelines worldwide. A survey questionnaire was developed based on the literature review and open-end expert interviews. Then, we performed expert consensus, discussion meeting, opinion collection, external examination, and the GRADE-TCM was formed eventually. RESULTS 265 Chinese and English TCM guidelines were included and analyzed. Five experts completed the open-end interviews. Ten methodological entries were summarized, screened and selected. One round of consensus was conducted, including a total of 22 experts and 220 valid questionnaire entries, concerning 1) selection of the GRADE, 2) GRADE-TCM upgrading criteria, 3) GRADE-TCM evaluation standard, 4) principles of consensus and recommendation, and 5) presentation of the GRADE-TCM and recommendation. Finally, consensus was reached on the above 10 entries, and the results were of high importance (with voting percentages ranging from 50 % to 81.82 % for "very important" rating) and strong reliability (with the Cr ranging from 0.93 to 0.99). Expert discussion meeting (with 40 experts), opinion collection (in two online platforms) and external examination (with 14 third-party experts) were conducted, and the GRADE-TCM was established eventually. CONCLUSION GRADE-TCM provides a new extended evidence-based evaluation standard for TCM guidelines. In GRADE-TCM, international evidence-based norms, characteristics of TCM intervention, and inheritance of TCM culture were combined organically and followed. This is helpful for localization of the GRADE in TCM and internationalization of TCM guidelines.

Self-Administered Acupressure for Probable Knee Osteoarthritis in Middle-Aged and Older Adults: A Randomized Clinical Trial. JAMA Netw Open 2024; 7:e245830. [PMID: 38639940 PMCID: PMC11031685 DOI: 10.1001/jamanetworkopen.2024.5830] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 11/17/2023] [Accepted: 02/12/2024] [Indexed: 04/20/2024] Open
Abstract
Importance The effects of self-administered acupressure (SAA) on knee osteoarthritis (OA) pain remain unclear. Objective To evaluate the effectiveness of SAA taught via a short training course on reducing knee OA pain in middle-aged and older adults. Design, Setting, and Participants This randomized clinical trial was conducted among community-dwelling individuals in Hong Kong who were aged 50 years or older with probable knee OA from September 2019 to May 2022. Interventions The intervention included 2 training sessions for SAA with a brief knee health education (KHE) session, in which participants practiced acupressure twice daily for 12 weeks. The control group (KHE only) received only education about maintaining knee health on the same schedule and duration. Main Outcomes and Measures The primary outcome was the numerical rating scale (NRS) pain score at 12 weeks. Other outcomes included Western Ontario and McMaster University Osteoarthritis Index, Short Form 6 Dimensions (SF-6D), Timed Up and Go, and Fast Gait Speed tests. Results A total of 314 participants (mean [SD] age, 62.7 [4.5] years; 246 [78.3%] female; mean [SD] knee pain duration, 7.3 [7.6] years) were randomized into intervention and KHE-only groups (each 157). At week 12, compared with the KHE-only group, the intervention group had a significantly greater reduction in NRS pain score (mean difference [MD], -0.54 points; 95% CI, -0.97 to -0.10 points; P = .02) and higher enhancement in SF-6D utility score (MD, 0.03 points; 95% CI, 0.003 to 0.01 points; P = .03) but did not have significant differences in other outcome measures. The cost-effectiveness acceptability curve demonstrated a greater than 90% probability that the intervention is cost-effective at a willingness to pay threshold of 1 GDP per capita. Conclusions and Relevance In this randomized clinical trial, SAA with a brief KHE program was efficacious and cost-effective in relieving knee pain and improving mobility in middle-aged and older adults with probable knee OA.

A longitudinal study on the change in sleep across three waves of the COVID-19 outbreaks in Hong Kong. Sleep Biol Rhythms 2024; 22:93-102. [PMID: 38476851 PMCID: PMC10899949 DOI: 10.1007/s41105-023-00486-w] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/31/2023] [Accepted: 08/19/2023] [Indexed: 03/14/2024]
Abstract
In the year 2020, Hong Kong experienced four COVID-19 epidemic waves. The present study aimed to examine the transition of sleep disturbances and explore its associated factors across the later three epidemic waves. Among the 1138 respondents who participated in an online survey at the second wave (T1, April 2020), 338 and 378 participants also completed a follow-up at the third (T2, August 2020) and fourth waves (T3, December 2020), respectively. Participants completed the Insomnia Severity Index and an investigator-designed questionnaire regarding potential factors associated with sleep change such as perceived risk of being infected, economic stress, and confidence in the government and health care professional. Sample of this study were mainly female (67.7%), married (50.3%), young adults (54.2%) with tertiary education (81.6%). Maintaining normal sleep was the most prevalent trajectory of sleep of all three waves (50.5%), followed by persistent insomnia (17.2%) and remitted insomnia (9.0%). Besides female, older-age and lower education level, the results showed that increment in worry about family being infected (adjusted risk ratio, RR = 1.28), perceived interference of daily lives (adjusted RR = 1.19), and economic distress (adjusted RR = 1.24) were significantly associated with the development of clinical insomnia during the three epidemic waves. These factors were also associated with worsening of other sleep parameters. Insomnia being persistent across the three waves of COVID-19 outbreaks was common. Increasing economic distress, daily interference, and worry about family members being infected were associated with an increasing risk of clinical insomnia across the three COVID-19 outbreaks.

Abstract
A good integration of dental implants and the surrounding soft tissue is essential to ensure the long-term effect of implant. In this review, we summarized the research progress of peri-implant soft tissue integration of dental titanium implants, with emphasis on the modification of the gingival interface of implants based on immune microenvironment regulation. This method influences the immune response around the implant by promoting the surface properties of implants, so as to enhance the peri-implant soft tissue integration. The purpose of this review is to provide reference for the related research and clinical application in the field of dental implantation.

Evaluating the effectiveness of video-game based swallowing function training in patients with dysphagia: study protocol for a randomized controlled trial. Trials 2023; 24:735. [PMID: 37974234 PMCID: PMC10655413 DOI: 10.1186/s13063-023-07738-7] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/27/2023] [Accepted: 10/17/2023] [Indexed: 11/19/2023] Open
Abstract
BACKGROUND Dysphagia can lead to serious complications such as aspiration and aspiration pneumonia, timely and effective rehabilitation training can improve the swallowing function of patients. However, the conventional rehabilitation training methods used in clinical settings have shortcomings such as poor adherence of patients. We present the study design of a randomized controlled trial that evaluated whether video-game based swallowing rehabilitation training can effectively improve swallowing in patients with dysphagia and whether it has additional benefits compared with conventional training methods to improve swallowing function and training compliance among patients with dysphagia. METHODS A randomized controlled trial with 4 weeks of intervention and 4 weeks of follow-up will be conducted in a rehabilitation center in Beijing, China. We will enroll 78 patients aged 18-80 years with dysphagia. Participants will be randomly assigned to the experimental group (video-game based swallowing function training) and the control group (conventional swallowing function training). All participants will receive 30 min of training per day, 5 times per week, for a total of 4 weeks. The primary outcome is swallowing function. Secondary outcomes include patients' quality of life, training compliance, and training satisfaction. Outcomes are assessed at baseline (pre-treatment), 4 weeks of treatment (post-treatment), and 8 weeks (follow-up), and the assessor is not aware of the participants' grouping. DISCUSSION The protocol describes a new rehabilitation training method for dysphagia, which involves participant eligibility recruitment, recruitment strategies, and data analysis plan. The results of the study will inform the rehabilitation training and clinical care management of swallowing function in patients with dysphagia. TRIAL REGISTRATION ClinicalTrials.gov, NCT05978700.

Abstract
Sixteen patients with recurrent high-grade glioma who were treated by domestic magnetic resonance-guided laser interstitial thermotherapy (MRgLITT) in the Neurosurgery Department of Xuanwu Hospital of Capital Medical University from 1st January 2021 to 31st December 2021 were prospectively included, with 11 males and 5 females, and aged 27-74 (50±16) years. The duration of surgery, the rate of ablation after surgery, and perioperative complications were assessed. The patients were followed up every 3 months to assess survival and progression. A total of 5 WHO grade Ⅲ patients and 11 WHO grade Ⅳ patients were included. The operation time was 144 (109, 176) min, 28 targeted lesions were detected, and the ablation rate [M (Q1, Q3)] was 91.0% (87.4%, 93.3%). After surgery, 2 patients (2/16) had decreased limb muscle strength, and no perioperative death or other serious complications occurred. The median time to a complete response was 12 (5, 14) months in WHO Grade Ⅲ patients, and one died 12 months after surgery, while the median time to a complete response was 3 (1, 8) months in 11 WHO Grade Ⅳ patients, with a total of 8 deaths at the last follow-up. Therefore, domestic MRgLITT has certain efficacy and safety in the treatment of recurrent high-grade glioma, providing a new option for patients with recurrent glioma.

Abstract
Severe acute dichlorvos poisoning is characterized by rapid onset, swift disease progression and serious complications. It frequently involves multiple organ failure (central, respiratory and circulatory systems), severe acidosis, and rare occurrences of gastric perforation. When secondary gastric perforation occurs, treatment becomes difficult and the prognosis of patients is poor. Thus, early and sufficient gastrointestinal decontamination is crucial. This article presented two cases of gastric perforation secondary to dichlorvos poisoning and discussed the causes of gastric perforation, as well is clinical diagnostic and treatment methods.

CXCR2 expression during melanoma tumorigenesis controls transcriptional programs that facilitate tumor growth. Mol Cancer 2023; 22:92.

Abstract
BACKGROUND Though the CXCR2 chemokine receptor is known to play a key role in cancer growth and response to therapy, a direct link between expression of CXCR2 in tumor progenitor cells during induction of tumorigenesis has not been established. METHODS To characterize the role of CXCR2 during melanoma tumorigenesis, we generated tamoxifen-inducible tyrosinase-promoter driven BrafV600E/Pten-/-/Cxcr2-/- and NRasQ61R/INK4a-/-/Cxcr2-/- melanoma models. In addition, the effects of a CXCR1/CXCR2 antagonist, SX-682, on melanoma tumorigenesis were evaluated in BrafV600E/Pten-/- and NRasQ61R/INK4a-/- mice and in melanoma cell lines. Potential mechanisms by which Cxcr2 affects melanoma tumorigenesis in these murine models were explored using RNAseq, mMCP-counter, ChIPseq, and qRT-PCR; flow cytometry, and reverse phosphoprotein analysis (RPPA). RESULTS Genetic loss of Cxcr2 or pharmacological inhibition of CXCR1/CXCR2 during melanoma tumor induction resulted in key changes in gene expression that reduced tumor incidence/growth and increased anti-tumor immunity. Interestingly, after Cxcr2 ablation, Tfcp2l1, a key tumor suppressive transcription factor, was the only gene significantly induced with a log2 fold-change greater than 2 in these three different melanoma models. CONCLUSIONS Here, we provide novel mechanistic insight revealing how loss of Cxcr2 expression/activity in melanoma tumor progenitor cells results in reduced tumor burden and creation of an anti-tumor immune microenvironment. This mechanism entails an increase in expression of the tumor suppressive transcription factor, Tfcp2l1, along with alteration in the expression of genes involved in growth regulation, tumor suppression, stemness, differentiation, and immune modulation. These gene expression changes are coincident with reduction in the activation of key growth regulatory pathways, including AKT and mTOR.

Abstract
Far infrared (FIR)-based clothing may alleviate sleep disturbance. This study aimed to explore the effects of FIR-emitting pajamas on sleep quality. This was a pilot randomized, sham-controlled trial. Forty subjects with poor sleep quality were randomized to FIR-emitting-pajamas and sham-pajamas groups in a 1:1 ratio. The primary outcome measure was the Pittsburgh Sleep Quality Index (PSQI). Other measures included the Insomnia Severity Index, and 7 day sleep diary, the Multidimensional Fatigue Inventory (MFI), the Hospital Anxiety and Depression Scale, the Epworth Sleepiness Scale, and the Satisfaction with Life Scale. Outcomes were measured at baseline and weeks 2, 4, and 6. Both groups showed within-group improvements in the PSQI score, but there was no significant difference between the two groups. However, FIR-emitting pajamas appeared to perform better than sham pajamas in reducing the MFI-physical score, with large effect sizes at three time points (dppc2 = 0.958, 0.841, 0.896); however, the differences were statistically insignificant. The intervention compliance was satisfactory. The effects of FIR-emitting pajamas on sleep quality were not superior to those in the control group. However, these pajamas may improve physical fatigue in adults with poor sleep quality, which warrants further exploration.

Experience of parents in delivering pediatric tuina to children with symptoms of attention deficit hyperactivity disorder during the COVID-19 pandemic: qualitative findings from focus group interviews. BMC Complement Med Ther 2023; 23:53. [PMID: 36804041 PMCID: PMC9938352 DOI: 10.1186/s12906-023-03891-3] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/17/2022] [Accepted: 02/15/2023] [Indexed: 02/19/2023] Open
Abstract
BACKGROUND Evidence suggests that pediatric tuina, a modality of traditional Chinese medicine (TCM), might have beneficial effects on the symptoms of attention deficit hyperactivity disorder (ADHD), such as overall improvements in concentration, flexibility, mood, sleep quality, and social functioning. This study was conducted to understand the facilitators and barriers in the delivery of pediatric tuina by parents to children with ADHD symptoms. METHODS This is a focus group interview embedded in a pilot randomized controlled trial on parent-administered pediatric tuina for ADHD in preschool children. Purposive sampling was employed to invite 15 parents who attended our pediatric tuina training program to participate voluntarily in three focus group interviews. The interviews were audio-recorded and transcribed verbatim. The data were analyzed through template analysis. RESULTS Two themes were identified: (1) facilitators of intervention implementation and (2) barriers to intervention implementation. The theme of the facilitators of intervention implementation included the subthemes of (a) perceived benefits to children and parents, (b) acceptability to children and parents, (c) professional support, and (d) parental expectations of the long-term effects of the intervention. The theme of barriers to intervention implementation included the subthemes of (a) limited benefits for children's inattention symptoms, (b) manipulation management difficulties, and (c) limitations of TCM pattern identification. CONCLUSION Perceived beneficial effects on the children's sleep quality and appetite and parent-child relationships, as well as timely and professional support, mainly facilitated the implementation of parent-administered pediatric tuina. Slow improvements in the children's inattention symptoms and the possible inaccuracies of online diagnosis were the dominant barriers of the intervention. Parents have high expectations for the provision of long-term professional support during their practice of pediatric tuina. The intervention presented here can be feasibly used by parents.

Abstract
Objective: To examine the outcomes of Tiantan first-aid protocol on critically ill patients with primary central nervous system lymphoma (PCNSL). Methods: The clinical data of 18 patients with PCNSL who were treated according to Tiantan first-aid protocol at Department of Neurosurgery,Beijing Tiantan Hospital, Capital Medical University from November 2019 to December 2021 were retrospectively analyzed. There were 9 males and 9 females, aged (56.9±11.1)years (range: 29 to 77 years). The median Karnofsky performance status(KPS) score at admission was 40 (range: 20 to 60). Three patients were mild coma, 3 were lethargy and 12 were conscious. The mean midline shift was 0.7 cm (range: 0 to 1.8 cm). After admission, all patients were treated according to the plan of rapid biopsy, rapid routine pathology and rapid salvage chemotherapy. The treatment procedures, clinical and radiographic outcomes, KPS score and adverse reactions of patients after chemotherapy were collected. Results: All of the 18 patients completed the first-aid treatment. The median duration from admission to the biopsy was 1 day (range: 0 to 5 days), from biopsy to routine pathological diagnosis was 1 day (range: 1 to 4 days) and from routine pathology to salvage chemotherapy was 1 day (range: 0 to 4 days). All the patients were pathologically confirmed with diffuse large B cell lymphoma, 1 patient was double-hit lymphoma. Seventeen patients underwent clinical remission and 1 died of cardiac dysfunction. The successful salvage rate was 17/18. Radiologically, complete remission was observed in 1 case, partial remission in 16 cases, and stable disease in 1 case. The median KPS score at discharge was 60 (range: 30 to 80). The mild gastrointestinal, hematological and hepatic adverse effects were observed after chemotherapy. Conclusion: Tiantan first-aid protocol is effective for critically ill patients with PCNSL, which has the merit to be popularly used and improved.

Abstract
BACKGROUND Beneficial effects of parent-administered pediatric tuina on ADHD in children have been reported in previous studies, but no rigorously designed randomized controlled trials (RCTs) have been conducted on it. OBJECTIVE To assess the feasibility and preliminary effects of parent-administered pediatric tuina for ADHD symptoms in preschoolers. METHODS This project was a two-arm, parallel, open-label, pilot RCT. Sixty-four participants were randomized into two groups at a 1:1 ratio. Parents in the parent-administered tuina group (n = 32) attended an online training program on pediatric tuina for ADHD and conduct this intervention on their children at home. Parents in the parent-child interaction group (n = 32) attended an online training about progressive muscle relaxation exercise and carried out parent-child interactive physical activities with their children at home. Both interventions were carried out every other day during a two-month intervention period, with each manipulation for at least 20 min. Feasibility outcomes included recruitment rate, consent rate, participants' adherence, retention rate, and adverse event. Outcomes were assessed at baseline, week 4, and week 8. The primary outcome measure was the Swanson, Nolan, and Pelham parent scale (SNAP); the secondary outcomes included preschool anxiety scale, children's sleep habits questionnaire, and parental stress scale. A mixed-method process evaluation embedded within the outcome evaluation was performed. RESULTS The recruitment rate was 12.8 per month. The consent rate was 98.5%. Good adherence was shown from the parent logbook. Four participants withdraw from the study. No severe adverse event was reported. For the SNAP total score, both groups showed improvement with moderate within-group effect size (Cohen's d > 0.5, all p < 0.001) and the between-group effect size was minimal (dppc2< 0.2, p > 0.05). Perceived improvements on children's appetite and sleep quality, and parent-child relationship was observed from the qualitative data. CONCLUSIONS The study design and the parent-administered pediatric tuina intervention were feasible. Parent-administered pediatric tuina provided beneficial effects on improving core hyperactivity/impulsivity symptoms in preschool children. Parents perceived improvements on children's appetite and sleep quality. Further large-scale are warranted.

METHODS The process evaluation comprises the following parts: (a) self-reported questionnaires on parents (n = 43), traditional Chinese medicine (TCM) practitioners (n = 2), outcome assessor (n = 1), and research assistant (n = 1); (b) parent logbook on parent-administered pediatric tuina (n = 32); and (c) focus group interview sessions (n = 15). Accomplishment of the self-report questionnaires was voluntary for all participants and compulsory for research personnel and TCM practitioners. The parent logbook on the intervention was filled out by all participants in the intervention group. Participants of focus group interviews were selected via purposive sampling, and data were analyzed with template analysis. Qualitative findings were summarized in tables, while the mean was calculated to reflect the quantitative findings. RESULTS Perceived benefits, acceptability of parents and children, and professional support from the research team facilitated the implementation of the intervention. Meanwhile, the TCM pattern identification using online mode may limit the accuracy and lead to parents doubting the precision of the TCM pattern. This limitation was regarded as a major barrier. Parents perceived improvements in terms of children's appetite, sleep quality, and parent-child relationship. Participants were generally satisfied with the settings of parent-administered pediatric tuina and showed satisfactory adherence to the implementation. CONCLUSIONS Implementation of parent-administered pediatric tuina intervention is feasible and acceptable. The intervention can be refined by improving the TCM pattern identification procedure and adjusting outcome settings in a fully powered study in the future.

Abstract
Chlorfenapyr is a moderately dangerous insecticide widely used in agriculture. The mortality of acute poisoning patients is high, and there is no effective treatment. This paper retrospectively analyzes the clinical data of two cases of compound chlorfenapyr poisoning. The main symptoms of the patients were high fever, sweating, gradual coma, increased creatine kinase and myoglobin, with delayed poisoning symptoms. Despite comprehensive treatment, both patients died eventually. It indicated that chlorfenapyr was highly toxic and had a high mortality. In addition to routine symptomatic treatment for patients with acute poisoning, blood purification treatment should be actively carried out in the early stage.

Effects of treatment processes on AOC removal and changes of bacterial diversity in a water treatment plant. JOURNAL OF ENVIRONMENTAL MANAGEMENT 2022; 311:114853. [PMID: 35276566 DOI: 10.1016/j.jenvman.2022.114853] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Subscribe] [Scholar Register] [Received: 11/13/2021] [Revised: 02/27/2022] [Accepted: 03/04/2022] [Indexed: 06/14/2023]
Abstract
The effectiveness of different treatment processes on assimilable organic carbon (AOC) removal and bacterial diversity variations was evaluated in a water treatment plant. The van der Kooij technique was applied for AOC analysis and responses of bacterial communities were characterized by the metagenomics assay. Results show that the AOC concentrations were about 93, 148, 43, 51, 37, and 38 μg acetate-C/L in effluents of raw water basin, preozonation, rapid sand filtration (RSF), ozonation, biofiltration [biological activated carbon (BAC) filtration], and chlorination (clear water), respectively. Increased AOC concentrations were observed after preozonation, ozonation, and chlorination units due to the production of biodegradable organic matters after the oxidation processes. Results indicate that the oxidation processes were the main causes of AOC formation, which resulted in significant increases in AOC concentrations (18-59% increment). The AOC removal efficiencies were 47, 28, and 60% in the RSF, biofiltration, and the whole system, respectively. RSF and biofiltration were responsible for the AOC treatment and both processes played key roles in AOC removal. Thus, both RSF and biofiltration processes would contribute to AOC treatment after oxidation. Sediments from the raw water basin and filter samples from RSF and BAC units were collected and analyzed for bacterial communities. Results from scanning electron microscope analysis indicate that bacterial colonization was observed in filter materials. This indicates that the surfaces of the filter materials were beneficial to bacterial growth and AOC removal via the adsorption and biodegradation mechanisms. Next generation sequencing analyses demonstrate that water treatment processes resulted in the changes of bacterial diversity and community profiles in filters of RSF and BAC. According to the findings of bacterial composition and interactions, the dominant bacterial phyla were Proteobacteria (41% in RSF and 56% in BAC) followed by Planctomycetes and Acidobacteria in RSF and BAC systems, which might affect the AOC biodegradation efficiency. Results would be useful in developing AOC treatment and management processes in water treatment plants.

Abstract
Objective: To investigate the safety and short-term efficacy of domestic magnetic resonance-guided laser interstitial thermotherapy (MRgLITT) in the treatment of drug-resistant epilepsy. Methods: Patients with drug-resistant epilepsy treated with a domestic MRgLITT system in the Department of Neurosurgery, Xuanwu Hospital, Capital Medical University from October 2020 to April 2021 were prospectively enrolled. The damage volume ratio was assessed immediately after surgery, and perioperative complications were recorded and followed up. The clinical safety and short-term efficacy were evaluated using the Engel classification. Results: A total of 22 patients were included, including 12 males and 10 females, aged from 3 to 45 years old [(24±13) years]. There were 5 cases of medial temporal lobe epilepsy (MTLE), 3 cases of hypothalamic hamartoma (HH), 7 cases of focal cortical dysplasia (FCD), and 7 cases of other types, respectively. The mean operation time and blood loss was (173±49) min and (3.7±1.6) ml. The postoperative length of hospital stay was (5.5±1.8) days, and the average damage volume ratio was 92.6%. Among them, only 2 patients (FCD of the parietal lobe) showed transient contralateral limb weakness, without any serious complications such as symptomatic intracranial hemorrhage and cerebral infarction. The follow-up time was 14 to 168 days. There were 13 Engel class Ⅰ cases (59.1%), 2 Engel class Ⅱ cases (9.1%), 2 Engel class Ⅲ cases (9.1%) and 5 Engel class Ⅳ cases (22.7%), respectively. Short-term incident-free rates were MTLE 5/5and FCD4/7, respectively. Conclusion: Domestic MRgLITT system is stable, reliable and safe in the treatment of drug-refractory epilepsy, and has better short-term efficacy in MTLE and FCD patients.

Abstract
BACKGROUND Currently there is limited information to guide health professionals regarding the optimal time frame to initiate safe and effective oral feedings to preterm infants. The study aims to revise and validate a streamlined version of the Traditional Chinese-Preterm Oral Feeding Readiness Assessment Scale, the TC-POFRAS®, and evaluate its construct validity in the clinical decisions regarding feeding readiness of preterm infants. METHODS Eighty-one clinically stable preterm infants were assessed using the TC-POFRAS for oral feeding readiness. Item-total correlation analysis was used to check if any item was inconsistent with the averaged TC-POFRAS scores. Cronbach's α coefficient was used to evaluate the inter-item consistency. Exploratory factor analysis was used to determine the coherence of variables to reorganize assessment domains. The revised version of TC-POFRAS (TC-POFRAS®) was developed and a new cut-off score based on discriminant accuracy was established. RESULTS Based on the results from statistical analysis, five items ("lips posture," "tongue posture," "biting reflex," "gag reflex," and "tongue cupping") were deleted from the original TC-POFRAS to form the TC-POFRAS®. The TC-POFRAS®'s global accuracy was 92.1%. The cut-off value of 19 was the one that presented the most optimization of sensitivity based on specificity. The TC-POFRAS® was reconstructed into corrected gestational age and five behavioral domains. CONCLUSIONS The TC-POFRAS® is considered a valid, safe, and accurate objective instrument to assist health professionals to initiate oral feeding of preterm infants.

Abstract
INTRODUCTION Massage is a popularly used complementary and alternative therapy. Previous randomised controlled trials have examined the effects of massage on children, and several systematic reviews have been conducted to synthesise these data. This study aims to assess and summarise the current evidence from published systematic reviews of controlled clinical trials on the practice of paediatric massage, specifically in infants and children aged < 5 years. METHODS The online databases MEDLINE, Embase, Health Technology Assessment Database, Cochrane Database of Systematic Reviews, Database of Abstracts of Reviews of Effects, Allied and Complementary Medicine, China National Knowledge Infrastructure and Wanfang Data will be searched from the inception onwards for evidence of the treatment effects. We will include systematic reviews of randomised control trials evaluating the effects and safety of massage therapy in infants and children aged < 5 years. The primary outcomes will be any physical or psychological outcome, and adverse effects on children. Secondary outcomes will include any physical or psychological outcome on caregivers. Two reviewers will independently screen the articles for inclusion as per the eligibility criteria. They will extract information from the included studies and assess the methodological quality of the included studies. A table will be used to summarise of information of the included studies, which includes the basic information, method and findings. The methodological quality of the included systematic reviews will be assessed by A Measurement Tool to Assess Systematic Reviews version 2 (AMSTAR 2). Extracted data from the included studies will be collected and presented using narrative approach. The pooled effect estimates for meta-analysed outcomes will be extracted when possible. If there is a discrepancy in results of two or more reviews on the same topic, then the causes of such discrepancy will be further explored. DISCUSSION This overview of systematic reviews will summarise the current evidence on massage, specifically for infants and children aged < 5 years. We will comprehensively present the positive effects and adverse effects of this intervention. Findings from this overview will be published in a peer-reviewed journal.

Abstract
BACKGROUND The ItchyQoL is an itch-specific patient-reported outcome measure used to assess quality of life in patients with chronic pruritus (CP). OBJECTIVES We aimed to assess and extend the psychometric properties of the ItchyQoL using classical test theory (CTT) and item response theory (IRT). METHODS Item characteristic curves were analysed to investigate whether the response categories were functioning optimally. Confirmatory factor analyses were carried out on the ItchyQoL prior to and after rescoring of the response categories. We conducted a Rasch analysis for the ItchyQoL with revised response options and assessed the mean fit residuals in addition to the assumptions of unidimensionality and local independence. RESULTS In total, 551 patients with CP from nine European countries completed the 22 items of the ItchyQoL. IRT analysis supported the revision of response options from five points to three. This revision was supported by excellent structural validity using CTT. The overall fit to the Rasch model was adequate. Unidimensionality was supported by the ItchyQoL overall scale and by the single subscales; however, local independence was violated in eight cases. CONCLUSIONS We suggest a revision of the response categories of the ItchyQoL from a 5-point to a 3-point scale. When this revision was applied, the ItchyQoL showed excellent structural validity according to CTT and IRT/Rasch. The calculation of an overall ItchyQoL sum score is allowed.

Electromoxibustion for knee osteoarthritis in older adults: A pilot randomized controlled trial. Complement Ther Clin Pract 2020; 41:101254. [PMID: 33190009 DOI: 10.1016/j.ctcp.2020.101254] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/07/2020] [Revised: 10/06/2020] [Accepted: 10/25/2020] [Indexed: 10/23/2022]
Abstract
BACKGROUND Electromoxibustion devices are commercially available and can be self-administered by patients. Nevertheless, little is known about the effectiveness and potential burn injury of these devices as this topic is under-investigated. OBJECTIVE To assess the preliminary effects and safety of an electromoxibustion (EM) device for improving knee pain and joint functions in older adults with knee osteoarthritis (KOA). DESIGN, SETTING, PARTICIPANTS AND INTERVENTION This was a pilot two-armed assessor-blinded randomized controlled trial to assess the effects of electromoxibustion (EM) on older adults with KOA. A total of 38 subjects aged 60 or above, with KOA for 3 months or above were recruited. Participants were randomized to the EM group or the knee health education group. The intervention group (n = 21) received 12 sessions of EM spanning across four weeks, while the control group (n = 17) received two sessions of knee health education. MAIN OUTCOME MEASURES Primary outcome included the pain severity Numerical Rating Scale (NRS) at baseline and week 4. Secondary outcomes included the Western Ontario and McMaster University Osteoarthritis Index (WOMAC), Short-Form Six-Dimension (SF6D), Timed Up & Go Test (TUG) and Fast Speed Gait (FSG). RESULTS Both groups showed a decreasing trend in knee pain intensity by NRS at post-intervention. There were also trends of improvement in the WOMAC score, TUG score, FGS test score and SF-6D score at week 4. Only a small between-group effect size (d = 0.13) was found, but medium between-group effects sizes were found in the WOMAC total score (d = 0.40) and WOMAC functional sub-score (d = 0.51). However, the differences were not statistically significant. CONCLUSION This study suggested that EM may be beneficial for KOA in older adults, particularly in terms of improving knee function. Replication of similar studies in larger RCTs is warranted to confirm the effectiveness of EM on reducing pain and knee function of older adults with KOA. TRAIL REGISTRATION NUMBER NCT04034394.

Abstract
Objective: To evaluate the airway and voice quality improvement in patients with bilateral vocal fold paralysis (BVFP) who underwent selective laryngeal reinnervation surgery. Methods: From January 2012 to December 2016, a retrospective study was conducted in 39 patients with BVFP who underwent selective laryngeal reinnervation surgery in Department of Otorhinolaryngology Head and Neck Surgery, the First Affiliated Hospital of Navy Medical University. All patients were examined by videostroboscopy, vocal function assessment, laryngeal electromyography and pulmonary function test before and after the surgery, and followed up for at least 2 years to evaluate the efficacy and safety of the surgery.Wilcoxon signed rank test was used to analyze the G score and VHI-10 score data. Paired t-test was used to analyze acoustic parameters, MPT values and pulmonary function parameters. Results: Postoperative infection and hemorrhage occurred in one patient separately.Videostroboscopic videos showed that at 4-8 months postoperatively, vocal folds in 35 patients achieved moderate or severe abduction during inspiration, 2 patients only achieved mild abduction, 2 patients showed no abduction,while all patients achieved adduction in bilateral vocal cords during phonation. The recovery rate of moderate-to-severe abduction was 89.7% (35/39), and these patients were decannulated successfully. At 12 months after operation, G score and VHI-10 score were significantly lower than those before operation (P<0.05), and the acoustic parameters jitter, shimmer, HNR and MPT were significantly improved (P<0.05). Most of the parameters of the pulmonary function test at 3 months postoperatively returned to the normal reference level, while the maximum inspiratory pressure (PImax) at 12 months after operation was still slightly lower than the normal level, but it was significantly improved compared with preoperative value (P<0.05). The EMG data at 12 months postoperatively showed full interference potentials in 37 patients in bilateral posterior cricoarytenoid muscles during inspiration, and full interference potentials in bilateralthyroarytenoid muscles during phonation. Obvious misdirected regeneration electric activitieswere found in two of them. Potentials in posterior cricoarytenoid muscle were weak in 2 cases with poor abduction. During long-term follow-up, only one case showed decreased abduction, but did not affect respiratory function. Conclusions: The selective laryngeal reinnervation procedure applied in the present study can restore physiological motion of vocal cords. The success rate was high, the curative effect was stable, and the complications were rare. It is worth of promotion.

Abstract
BACKGROUND Medication and behavior therapy are the conventional treatments for attention deficit hyperactivity disorder (ADHD), but they have limitations for preschool children. Evidence suggests that pediatric tuina, which is a modality of traditional Chinese medicine, might have beneficial effects on this condition. OBJECTIVE To assess the feasibility of conducting an RCT in terms of recruitment, use, and acceptability of the parent-administered pediatric tuina for ADHD symptoms in preschoolers. METHODS It is a single-center, two-arm, parallel, open-label, pilot randomized controlled trial (RCT). Sixty children with pre-specified ADHD symptoms (hyperactivity, anxiety, and sleep disturbance) together with one of their parents will be recruited and randomized into two groups at a 1:1 ratio. Parents in the parent-administered tuina group (intervention group, n = 30) will attend an online training program to learn pediatric tuina skills for ADHD symptoms and conduct this treatment on their children at home. Parents in the parent-child interaction group (comparison group, n = 30) will attend an online training about progressive muscle relaxation exercise and do this exercise with their children at home. Additional teaching materials will be provided to the participants in both groups. Both interventions should be carried out every other day during a 2-month treatment period, with each time around 20 min. Assessment will be performed at baseline, week 4, and week 8. The primary outcome measure is the Swanson, Nolan, and Pelham parent scale; the secondary outcomes include preschool anxiety scale, children's sleep habits questionnaire, and parental stress scale. A process evaluation embedded within the outcome evaluation will be performed. Differences in the scale scores and test parameters between groups will be examined using a linear mixed-effects model. Qualitative data will be analyzed using thematic content analysis, facilitated by QSR NVivo. DISCUSSION This study will provide evidence on the acceptability and feasibility of pediatric tuina for ADHD in preschool children. The process evaluation will help to better understand the facilitators and barriers of the intervention functioning. TRIAL REGISTRATION The study was registered at ClinicalTrials.gov (Identifier: NCT04237259 ) on 14 February 2020. Protocol version: 2; date, 23 June 2020.

MK-8719, a Novel and Selective O-GlcNAcase Inhibitor That Reduces the Formation of Pathological Tau and Ameliorates Neurodegeneration in a Mouse Model of Tauopathy. J Pharmacol Exp Ther 2020; 374:252-263. [PMID: 32493725 DOI: 10.1124/jpet.120.266122] [Citation(s) in RCA: 41] [Impact Index Per Article: 10.3] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/06/2020] [Accepted: 06/01/2020] [Indexed: 01/01/2023] Open
Abstract
Deposition of hyperphosphorylated and aggregated tau protein in the central nervous system is characteristic of Alzheimer disease and other tauopathies. Tau is subject to O-linked N-acetylglucosamine (O-GlcNAc) modification, and O-GlcNAcylation of tau has been shown to influence tau phosphorylation and aggregation. Inhibition of O-GlcNAcase (OGA), the enzyme that removes O-GlcNAc moieties, is a novel strategy to attenuate the formation of pathologic tau. Here we described the in vitro and in vivo pharmacological properties of a novel and selective OGA inhibitor, MK-8719. In vitro, this compound is a potent inhibitor of the human OGA enzyme with comparable activity against the corresponding enzymes from mouse, rat, and dog. In vivo, oral administration of MK-8719 elevates brain and peripheral blood mononuclear cell O-GlcNAc levels in a dose-dependent manner. In addition, positron emission tomography imaging studies demonstrate robust target engagement of MK-8719 in the brains of rats and rTg4510 mice. In the rTg4510 mouse model of human tauopathy, MK-8719 significantly increases brain O-GlcNAc levels and reduces pathologic tau. The reduction in tau pathology in rTg4510 mice is accompanied by attenuation of brain atrophy, including reduction of forebrain volume loss as revealed by volumetric magnetic resonance imaging analysis. These findings suggest that OGA inhibition may reduce tau pathology in tauopathies. However, since hundreds of O-GlcNAcylated proteins may be influenced by OGA inhibition, it will be critical to understand the physiologic and toxicological consequences of chronic O-GlcNAc elevation in vivo. SIGNIFICANCE STATEMENT: MK-8719 is a novel, selective, and potent O-linked N-acetylglucosamine (O-GlcNAc)-ase (OGA) inhibitor that inhibits OGA enzyme activity across multiple species with comparable in vitro potency. In vivo, MK-8719 elevates brain O-GlcNAc levels, reduces pathological tau, and ameliorates brain atrophy in the rTg4510 mouse model of tauopathy. These findings indicate that OGA inhibition may be a promising therapeutic strategy for the treatment of Alzheimer disease and other tauopathies.

Abstract
BACKGROUND AND PURPOSE Congenital muscular torticollis (CMT) is a musculoskeletal condition occurring in infants and children. This systematic review is conducted to summarize the current evidence on the effects and safety of TCM massage therapy for the treatment of CMT in infants and children. METHODS We searched for randomized controlled trials (RCTs) and quasi-RCTs on TCM massage for CMT in PubMed, Embase, CENTRAL, CINAHL, AMED, PsycINFO, Ovid MEDLINE, TCMLARS, ICTRP, CSTJ, CNKI, Wanfang Data, CBM, Taiwan Electronic Periodical Services, and the Index to Taiwan Periodical Literature System. Two reviewers conducted the data collection and analysis separately. Cochrane's collaboration tool was used to assess the risk of bias, and GRADEpro was used to assess the overall quality of the evidence. RevMan 5.3 software was used for data analysis with a random-effect model. RESULTS A systematic review of six RCTs and one quasi-RCT was conducted with a meta-analysis of two of the RCTs. Pooled analysis showed that TCM massage has similar effects to those of stretching therapy on CMT symptoms in terms of effective rate (risk ratio: 1.00, 95% CI: 0.94-1.06; I2 = 0%; P = 0.99). CONCLUSION Evidence suggests that TCM massage therapy is beneficial for treating CMT in infants and children. Further clinical trials with high-quality methodologies need to be conducted.

Abstract
Objective: Comparison of the permeability between the rabbit cornea and sclera ex vivo by determining the concentration of gatifloxacin using LC-MS/MS method, which may provide the basis for a new route of drug administration. Methods: Experimental study. The permeability of the cornea and sclera in healthy male New Zealand rabbits was evaluated by using Franz diffusion pool. We chose both gatifloxacin ophthalmic solution and gel as the test drugs, and calculated the cumulative permeation amounts (Qn), apparent permeability coefficient(P(app)). Results: The linear range of gatifloxacin was 5-1 000 ng/ml. The intra-day and inter-day precision was 1.7% -2.8% and 1.0% - 2.3%. Q(n) and P(app) of gatifloxacin ophthalmic solution in cornea and sclera ex vivo were 177.57, 517.52 μg/cm(2) and 4.34, 12.51 cm/s respectively, whereas that of gatifloxacin ophthalmic gel were 151.87, 411.05 μg/cm(2) and 3.66, 9.21 cm/s. Conclusion: This validated method could be applied to determine the gatifloxacin. The cumulative permeation amounts and apparent permeability coefficient of sclera are significantly higher than that of cornea for both ophthalmic solution and gel, suggesting that the development of a new route of drug administration based on sclera may have potential advantage.

Application of γ-PGA as the primary carbon source to bioremediate a TCE-polluted aquifer: A pilot-scale study. CHEMOSPHERE 2019; 237:124449. [PMID: 31376698 DOI: 10.1016/j.chemosphere.2019.124449] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.2] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 02/07/2019] [Revised: 07/13/2019] [Accepted: 07/23/2019] [Indexed: 06/10/2023]
Abstract
The effectiveness of using gamma poly-glutamic acid (γ-PGA) as the primary carbon and nitrogen sources to bioremediate trichloroethene (TCE)-contaminated groundwater was studied in this pilot-scale study. γ-PGA (40 L) solution was injected into the aquifer via the injection well (IW) for substrate supplement. Groundwater samples were collected from monitor wells and IW and analyzed for TCE and its byproducts, geochemical indicators, dechlorinating bacteria, and microbial diversity periodically. Injected γ-PGA resulted in an increase in total organic carbon (TOC) (up to 9820 mg/L in IW), and the TOC biodegradation caused the formation of anaerobic conditions. Increased ammonia concentration (because of amine release from γ-PGA) resulted in the neutral condition in groundwater, which benefited the growth of Dehalococcoides. The negative zeta potential and micro-scale diameter of γ-PGA allowed its globule to distribute evenly within soil pores. Up to 93% of TCE removal was observed (TCE dropped from 0.14 to 0.01 mg/L) after 59 days of γ-PGA injection, and TCE dechlorination byproducts were also biodegraded subsequently. Next generation sequence (NGS) analyses were applied to determine the dominant bacterial communities. γ-PGA supplement developed reductive dechlorinating conditions and caused variations in microbial diversity and dominant bacterial species. The dominant four groups of bacterial communities including dechlorinating bacteria, vinyl chloride degrading bacteria, hydrogen producing bacteria, and carbon biodegrading bacteria.

Abstract
BACKGROUND Most people with chronic kidney disease (CKD) are not aware of their condition. OBJECTIVES To assess screening criteria in identifying a population with or at high risk for CKD and to determine their level of control of CKD risk factors. METHOD CKD Health Evaluation Risk Information Sharing (CHERISH), a demonstration project of the Centers for Disease Control and Prevention, hosted screenings at 2 community locations in each of 4 states. People with diabetes, hypertension, or aged ≥50 years were eligible to participate. In addition to CKD, screening included testing and measures of hemoglobin A1C, blood pressure, and lipids. -Results: In this targeted population, among 894 people screened, CKD prevalence was 34%. Of participants with diabetes, 61% had A1C < 7%; of those with hypertension, 23% had blood pressure < 130/80 mm Hg; and of those with high cholesterol, 22% had low-density lipoprotein < 100 mg/dL. CONCLUSIONS Using targeted selection criteria and simple clinical measures, CHERISH successfully identified a population with a high CKD prevalence and with poor control of CKD risk factors. CHERISH may prove helpful to state and local programs in implementing CKD detection programs in their communities.

Abstract
BACKGROUND Chronic pruritus (CP) is a frequently occurring symptom in inflammatory dermatoses, causing a high burden and limitations to health-related quality of life (HRQoL). OBJECTIVE The ItchyQoL was developed to assess the impairment to HRQoL in patients with CP. However, it has only been validated in English and German. Here, we report the validation in several languages across Europe. METHODS After professional translation, the versions of ItchyQoL were digitized for use as a tablet application. Validation was performed in clinics for dermatology in Austria, France, Germany, Italy, Poland, Russia, Spain, Switzerland and Turkey. RESULTS Five hundred and thirty-five patients with either contact dermatitis, chronic prurigo - nodular type, psoriasis vulgaris, lichen planus or mycosis fungoides/Sézary syndrome and with CP ≥ 3 on the numerical rating scale were included. ItchyQoL showed a high level of consistency (Cronbach's-α, all: 0.95) and test-retest reliability (intraclass correlation: 0.91). It strongly correlated with the Dermatology Life Quality Index (r = 0.72, P < 0.001) and moderately correlated with itch intensity scales in the study population (visual analogue scale r = 0.46; numerical rating scale r = 0.51; verbal rating scale r = 0.51, for all: P < 0.001). CONCLUSION ItchyQoL is now also validated in French, Italian, Polish, Russian, Spanish and Turkish and can be used in clinical trials in countries speaking these languages.

Abstract
Utilization of bacterial volatilization can be problematic to remediate mercury (Hg)-contaminated soils because most of the Hg in soils is bound to soil particles. The objective of this study was to develop a two-stage system (chemical extraction followed by microbial reduction) for Hg-contaminated soil remediation. The tasks were to (1) select the extraction reagents for Hg extraction, (2) assess the effects of extraction reagents on the growth of Hg-reducing bacterial strains, and (3) evaluate the effectiveness of Ca2+ and Mg2+ addition on merA gene (Hg reductase) induction. Bacterial inhibition was observed with the addition of 0.1 M ethylenediaminetetraacetic acid or citric acid. Up to 65% of Hg was biotransformed (Hg concentration = 69 mg/kg) from the soils after a 24 h extraction using 0.5 M ammonium thiosulfate. Ca2+ and Mg2+ were selected because they have the same electric charge as Hg and the studied groundwater contained high concentrations of Ca2+ and Mg2+. Results showed that the addition of 200 mg/L Ca2+ or 650 mg/L Mg2+ could reach effective merA induction. In the two-stage experiment, 120 mg/kg Hg-contaminated soils were extracted with 2 rounds of extraction processes for 10 h using 0.5 M ammonium thiosulfate. Approximately 77% of Hg was extracted from the soils after the first-step extraction process. Up to 81% of Hg2+ was transformed from the washing solution via the biotransformation processes with Enterobacter cloacae addition and Ca2+ and Mg2+ supplementation. The two-stage remedial system has the potential to be developed into a practical technology to remediate Hg-contaminated sites.

Abstract
Objective:To evaluate the feasibility and long-term outcome of radiofrequency coblation combined with silicon stent implantation in the treatment of recurrent laryngeal papilloma with extensive lesions. Method:From March 2009 to April 2016, a total of 13 patients (8 males, 5 females; aged 28-67 years) who suffered recurrent laryngeal papilloma were enrolled in this retrospective study. All the cases had undergone at least one operation at other hospitals before this hospitalization. The recurrence interval (RI) of these cases ranged from 2 to 6 months. Video-laryngoscopy or stroboscopy were preformed preoperatively and postoperatively, as well as vocal function assessment. These cases underwent radiofrequency coblationin combination of different stent implantation (member, 7 cases; tube, 4 cases; T-shaped tube, 2 cases) under general anesthesia. The follow-up was 12 to 76 months. Result:Laryngoscopy revealed that the lesions mainly located in the vocal folds, anterior commissure, ventricular band, posterior commissure, epiglottis and even in subglottic area. Varying extent of mucosal adhesion of anterior or/and posterior commissure were observed in all cases, and two cases suffered mild subglottic tracheal stenosis. Two to six weeks after surgery, the silicon stent were removed and no mucosal adhesion were found except for 2 cases who suffered mucosal adhesion of anterior commissure again. Compared to preoperative scores, VHI-10 and G scores showed the significant improvement of voice quality postoperatively in all cases. The recurrence of papilloma was observed in 3 cases during 1-year follow-up, and 4 cases during 2-year follow-up, no recurrence in 6 cases. These recurrence lesions mainly located in ventricular band, subglottic area and trachea. However, no recurrence occurred in these cases who received ablation again. No serious complications were observed in these cases. Conclusion:Radiofrequency ablation may be an effective approach in the treatment of recurrent laryngeal papilloma with extensive lesions. One-stage application of suitable silicon stents can effectively prevent the adhesion of the wound and the onset oflaryngo-tracheal stenosis, and improve the quality of voice.

Abstract
Intracranial hypertension leading to brain stem herniation is a major cause of death in fulminant hepatic failure (FHF). Mannitol, barbiturates, and hyperventilation have been used to treat brain swelling, but most patients are either refractory to medical management or cannot be treated because of concurrent medical problems or side effects. In this study, we examined whether allogeneic hepatocellular transplantation may prevent development of intracranial hypertension in pigs with experimentally induced liver failure. Of the two preparations tested—total hepatectomy (n = 47), and liver devascularization (n = 16)—only pigs with liver ischemia developed brain edema provided, however, that animals were maintained normothermic throughout the postoperative period. This model was then used in transplantation studies, in which six pigs received intrasplenic injection of allogeneic hepatocytes (2.5 × 109 cells/pig) and 3 days later acute liver failure was induced. In both models (anhepatic state, liver devascularization), pigs allowed to become hypothermic had significantly longer survival compared to those maintained normothermic. Normothermic pigs with liver ischemia had, at all time points studied, ICP greater than 20 mmHg. Pigs that received hepatocellular transplants had ICP below 15 mmHg until death; at the same time, cerebral perfusion pressure (CPP) in transplanted pigs was consistently higher than in controls (45 ± 11 mmHg vs. 16 ± 18 mmHg; p < 0.05). Spleens of transplanted pigs contained clusters of viable hepatocytes (hematoxylin-eosin, CAM 5.2). It was concluded that removal of the liver does not result in intracranial hypertension; hypothermia prolongs survival time in both anhepatic pigs and pigs with liver devascularization, and intrasplenic transplantation of allogeneic hepatocytes prevents development of intracranial hypertension in pigs with acute ischemic liver failure.

Abstract
To enhance the reductive dechlorination of 1,2-dichloroethane (DCA) in groundwater, substrate injection may be required. However, substrate biodegradation causes groundwater acidification and sulfide production, which inhibits the bacteria responsible for DCA dechlorination and results in an odor problem. In the microcosm study, the effectiveness of the addition of ferrous sulfate (FS), desulfurization slag (DS), and nanoscale zero-valent iron (nZVI) on acidification and sulfide control was studied during reductive dechlorination of DCA, and the emulsified substrate (ES) was used as the substrate. Up to 94% of the sulfide was removed with FS and DS addition (0.25 wt%) (initial DCA concentration = 13.5 mg/L). FS and DS amendments resulted in the formation of a metal sulfide, which reduced the hydrogen sulfide concentration as well as the subsequent odor problem. Approximately 96% of the DCA was degraded under reductive dechlorination with nZVI or DS addition using ES as the substrate. In microcosms with nZVI or DS addition, the sulfide concentration was reduced to less than 15 μg/L. Acidification can be controlled via hydroxide ions production after nZVI oxidation and reaction of free CaO (released from DS) with water, which enhanced DCA dechlorination. The quantitative polymerase chain reaction results confirmed that the microcosms with nZVI added had the highest Dehalococcoides population (up to 2.5 × 10(8) gene copies/g soil) due to effective acidification control. The α-elimination mechanism was the main abiotic process, and reductive dechlorination dominated by Dehalococcides was the biotic mechanism that resulted in DCA removal. More than 22 bacterial species were detected, and dechlorinating bacteria existed in soils under alkaline and acidic conditions.

Abstract
Objective:To investigate the application of the reconstruction methods for hypopharyngeal and cervical esophageal defects due to the resection of hypopharyngeal cancer and advanced laryngeal cancer between free fasciocutaneous flaps and free jejunium transfer.We compared the superiorities and inferiorities of these two reconstruction methods. Method:Retrospective review of the archives of 56 patients from 2000 to 2010 who underwent pharyngoesophageal reconstruction with free flaps (n=32) or free jejunal transfer(n=24),comparison of indications,complications, hospitalization duration, swallowing function recovery and postoperative survival time. Result:The overall 3 year survival rate of free flap group and free jejunal transfer group was 59.3%,55.7% respectively; the overall 5 year survival rate was 38.5%,37.1% respectively. The overall rate of complication rate was 18.8%, 16.7% respectively. The patients with free flaps had higher incidence rate of fistula and scarring in the donor site and lower incidence rate of hues and stricture than the ones with free jejunal transfers. The mean hospitalization duration was (15.00±7.06) days and(13.00±6.75) days. The mean time of first oral food intake was(13.00±5.83)days and (11.00±6.67) days. The differences between two groups had no statistical significance(P>0.05). Conclusion:Free flaps and free jejunium transfer are the two most common reconstruction methods for the hypopharyngeal and cervical esophageal defects. Each has its own advantages and disadvantages respectively. We should choose reconstruction method according to the site and extent of the hypopharyngeal and cervical esophageal defects, preoperative and postoperative radiotherapy requirement.

Abstract
Although management of multiple myeloma has changed substantially in the last decade, it is unknown whether the burden of ESRD due to multiple myeloma has changed, or whether survival of patients with multiple myeloma on RRT has improved. Regarding ESRD due to multiple myeloma necessitating RRT in the United States, we evaluated temporal trends between 2001 and 2010 for demography-adjusted incidence ratios, relative to rates in 2001-2002, and mortality hazards from RRT initiation, relative to hazards in 2001-2002. In this retrospective cohort study, we used the US Renal Data System database (n=1,069,343), 2001-2010, to identify patients with ESRD due to multiple myeloma treated with RRT (n=12,703). Demography-adjusted incidence ratios of ESRD from multiple myeloma decreased between 2001-2002 and 2009-2010 in the overall population (demography-adjusted incidence ratio 0.82; 95% confidence interval, 0.79 to 0.86) and in most demographic subgroups examined. Mortality rates were 86.7, 41.4, and 34.4 per 100 person-years in the first 3 years of RRT, respectively, compared with 32.3, 20.6, and 21.3 in matched controls without multiple myeloma. Unadjusted mortality hazards ratios declined monotonically after 2004 to a value of 0.72; 95% confidence interval, 0.67 to 0.77 in 2009-2010, and declines between 2001-2002 and 2008-2009 were observed (P<0.05) in most demographic subgroups examined. Findings were similar when adjustment was made for demographic characteristics, comorbidity markers, and laboratory test values. These data suggest the incidence of RRT from multiple myeloma in the United States has decreased in the last decade, and clinically meaningful increases in survival have occurred for these patients.

Objective:To explore the diagnosis, treatment and curative effect of cervical cellulitis combineing mediastinal pleural abscess. Method:Clinical data of 37 patients with the cervical cellulitis and mediastinal pleural abscess were analyzed, all patients were confirmed using ultrasond, X-ray, CT, puncture and microbiology examination. The result will analysis the diagnosis, treatment and curative effect through the comparison of conservative treatment and surgical treatment. Result:Twenty-three cases of patients were underwent tracheotomy because of difficulty in breathing and successfully extubated after treatment. Nine cases of patients were given anti-infection treatment and recovered after conservative treatment. Twenty-one cases of neck multiple pus cavity were underwent cavity incision, full removal of necrotic tissue and pipe flushing; 7 cases of patients with neck and mediastinal abscess and within which 2 cases were with toxic shock were underwent adequate drainage of lavage and abscess incision through jugular joint path; the companion of pyothorax in 2 cases were underwent the chest closed drainage. All patients were giving sensitive antibiotic after drug sensitive test, anti-shock treatment and supportive treatment. All the patients were recovered and discharged. The average hospitalization days with conservative treatment of these patients were 15.7 days, and the average hospitalization days with surgical treatment of patients were 25.3 days. Conclusion:The condition of cervical cellulitis is complex, a few case can be cured with conservative treatment. The others progress rapidly when merging mediastinal pleural abscess can cause serious complications, surgical treatment is risky, fully abscess incision, lavage drainage and combine with sensitive antibiotics and supportive treatment are the keys to therapy.

Abstract
Management of hemolytic uremic syndrome (HUS) has evolved rapidly, and optimal treatment strategies are controversial. However, it is unknown whether the burden of end-stage renal disease (ESRD) from HUS has changed, and outcomes on dialysis in the United States are not well described. We retrospectively examined data for patients initiating maintenance renal replacement therapy (RRT) (n = 1,557,117), 1995-2010, to define standardized incidence ratios (SIRs) and outcomes of ESRD from HUS) (n = 2241). Overall ESRD rates from HUS in 2001-2002 were 0.5 cases/million per year and were higher for patients characterized by age 40-64 years (0.6), ≥65 years (0.7), female sex (0.6), and non-Hispanic African American race (0.7). Standardized incidence ratios remained unchanged (P ≥ 0.05) between 2001-2002 and 2009-2010 in the overall population. Compared with patients with ESRD from other causes, patients with HUS were more likely to be younger, female, white, and non-Hispanic. Over 5.4 years of follow-up, HUS patients differed from matched controls with ESRD from other causes by lower rates of death (8.3 per 100 person-years in cases vs. 10.4 in controls, P < 0.001), listing for renal transplant (7.6 vs. 8.6 per 100 person-years, P = 0.04), and undergoing transplant (6.9 vs. 9 per 100 person-years, P < 0.001). The incidence of ESRD from HUS appears not to have risen substantially in the last decade. However, given that HUS subtypes could not be determined in this study, these findings should be interpreted with caution.

Abstract
This article introduces the second revision of the Australian and New Zealand consensus guidelines for the use of antifungal agents in the haematology/oncology setting. The current update occurs within the context of a growing population at risk of invasive fungal disease, improved understanding of risk factors, availability of new diagnostic tests, a much-expanded evidence base and changing clinical paradigms. Here, we provide an overview of the history and purpose of the guidelines, including changes in scope since the last clinical update was published in 2008. The process for development, and for enabling review of draft recommendations by end-users and other relevant stakeholders, is described. The approach to assigning levels of evidence and grades of recommendation is also provided, along with a comparison to international grading systems.
