Abstract
Objective: To explore potential predictors of refractory Mycoplasma pneumoniae pneumonia (RMPP) in early stage. Methods: The prospective multicenter study was conducted in Zhejiang, China from May 1st, 2019 to January 31st, 2020. A total of 1 428 patients with fever >48 hours to <120 hours were studied. Their clinical data and oral pharyngeal swab samples were collected; Mycoplasma pneumoniae DNA in pharyngeal swab specimens was detected. Patients with positive Mycoplasma pneumoniae DNA results underwent a series of tests, including chest X-ray, complete blood count, C-reactive protein, lactate dehydrogenase (LDH), and procalcitonin. According to the occurrence of RMPP, the patients were divided into two groups, RMPP group and general Mycoplasma pneumoniae pneumonia (GMPP) group. Measurement data between the 2 groups were compared using Mann-Whitney U test. Logistic regression analyses were used to examine the associations between clinical data and RMPP. Receiver operating characteristic (ROC) curves were used to analyse the power of the markers for predicting RMPP. Results: A total of 1 428 patients finished the study, with 801 boys and 627 girls, aged 4.3 (2.7, 6.3) years. Mycoplasma pneumoniae DNA was positive in 534 cases (37.4%), of whom 446 cases (83.5%) were diagnosed with Mycoplasma pneumoniae pneumonia, including 251 boys and 195 girls, aged 5.2 (3.3, 6.9) years. Macrolides-resistant variation was positive in 410 cases (91.9%). Fifty-five cases were with RMPP, 391 cases with GMPP. The peak body temperature before the first visit and LDH levels in RMPP patients were higher than that in GMPP patients (39.6 (39.1, 40.0) vs. 39.2 (38.9, 39.7) ℃, 333 (279, 392) vs. 311 (259, 359) U/L, both P<0.05). Logistic regression showed the prediction probability π=exp (-29.7+0.667×Peak body temperature (℃)+0.004×LDH (U/L))/(1+exp (-29.7+0.667×Peak body temperature (℃)+0.004 × LDH (U/L))), the cut-off value to predict RMPP was 0.12, with a consensus of probability forecast of 0.89, sensitivity of 0.89, and specificity of 0.67; and the area under ROC curve was 0.682 (95%CI 0.593-0.771, P<0.01). Conclusion: In MPP patients with fever over 48 to <120 hours, a prediction probability π of RMPP can be calculated based on the peak body temperature and LDH level before the first visit, which can facilitate early identification of RMPP.

Abstract
Objective: To investigate the distribution characteristics of cognition-related lifestyles of elderly in communities and explore the integrated effects on early cognitive decline. Methods: The participants were from the Project of Prevention and Intervention of Neurodegenerative Disease for Elderly in China. A total of 2 537 older adults aged ≥60 years without dementia in the 2015 baseline survey and the 2017 follow-up survey were included. The information about their cognition-related lifestyles, including physical exercise, social interaction, leisure activity, sleep quality, smoking status, and alcohol consumption, were collected through questionnaire survey and the integrated scores were calculated. Multivariate logistic regression analysis was used to assess the association between integrated cognition-related lifestyle score and early cognitive decline. Results: In the 2 537 older adults surveyed, 28.7% had score of 5-6, while only 4.8% had high scores for all 6 healthy lifestyles. Significant differences in healthy lifestyle factor distributions were observed between men and women. Multivariate logistic regression model showed that the risks for early cognitive decline in the older adults who had lifestyle score of 4 and 5-6 were lower than that in those with lifestyle score of 0-3 (OR=0.683, 95%CI: 0.457-1.019; OR=0.623, 95%CI: 0.398-0.976; trend P=0.030). In the women, the risks for early cognitive decline was lower in groups with score of 4 and 5-6 than in group with score of 0-3 (OR=0.491, 95%CI: 0.297-0.812; OR=0.556, 95%CI: 0.332-0.929; trend P=0.024). Conclusion: Cognition-related healthy lifestyles are associated with significantly lower risk for early cognitive decline in the elderly, especially in women.

Abstract
Objective: To examine the association between smoking status and related mortality among elderly people aged 60 and above in urban and rural areas of Beijing City. Methods: Based on Beijing City Elderly Comprehensive Health Cohort Study from 2009 to 2014, a total of 4 499 eligible older adults included in the baseline survey were followed up and investigated to collect information on survival and death. The Cox proportional hazards regression model was used to estimate hazard ratios (HRs) and corresponding 95% confidence intervals (CIs), and the dose-response relationship was estimated between the smoking index, the years of quitting and mortality. Results: The median (IQR) age of 4 499 subjects was 70.00 (10.00) years old, including 1 814 (40.32%) males. The proportion of non-smokers, former smokers and current smokers was 69.50% (3 127/4 499), 13.20% (594/4 499) and 17.30% (778/4 499), respectively. After adjusting for confounding factors such as demographic and sociological characteristics, lifestyle, etc., the results of multivariate Cox regression analysis showed that, compared to non-smokers, former smokers had a 30.6% increased risk of all-cause mortality [HR (95%CI): 1.306 (1.043-1.636)] and the HR (95%CI) of all-cause, malignant tumor and lung cancer mortality among current smokers has increased by 50.0% [HR (95%CI): 1.500 (1.199-1.877)], 80.3% [HR (95%CI): 1.803 (1.226-2.652)] and 212.6% [HR (95%CI): 3.126 (1.626-6.012)], respectively. The smoking index was positively associated with the increased risk of all-cause, malignant tumor and lung cancer mortality, while the years of smoking cessation were negatively associated with that risk (P<0.05). Conclusion: Smoking is associated with tobacco-related mortality among elderly people in Beijing City.

Abstract
Objective: To investigate the distribution characteristics of sex hormones and their relationship with all-cause mortality in Hainan female centenarians. Methods: All the subjects were from China Hainan Centenarian Cohort Study. A total of 717 female centenarians were included in the final analysis. Kaplan-Meier method was used to draw the survival curve, and Cox proportional hazard regression was used to analyze the relationship between sex hormones and survival time. Results: The M(Q1, Q3) of estradiol and progesterone among female centenarians was 32.60 (18.40, 58.70) pmol/L and 0.62 (0.32, 1.01) nmol/L. The estradiol (pmol/L) and progesterone (nmol/L) in the survival and death groups were 26.65 vs.37.80, 0.54 vs.0.69, respectively, with statistical differences (P<0.05). Cox multivariate analysis showed that estradiol and progesterone were significantly associated with death (P<0.05), the hazard ratio (HR) of estradiol Q4 was 1.58 (95%CI: 1.17-2.15), and the HR of progesterone Q3 was 1.53 (95%CI: 1.10-2.12), HR for Q4 was 1.63 (95%CI: 1.15-2.32). Subgroup and cross-analysis showed that estradiol was statistically significant with hypertension, diabetes, and low high-density lipoprotein cholesterol (P<0.05), and progesterone interacted with diabetes (P=0.016), while testosterone interacted with low high-density lipoprotein cholesterol (P=0.034). Conclusion: It is suggested that the estrogen levels of female centenarians in Hainan were associated with a higher mortality risk and an increased risk of cardiovascular metabolic disease (such as diabetes, hypertension, and abnormal lipid metabolism).

Abstract
Objective: To explore the efficacy and safety of endoscopic diaphragm incision in pediatric congenital duodenal diaphragm. Methods: Eight children with duodenal diaphragm treated by endoscopic diaphragm incision in the Department of Gastroenterology of Guangzhou Women and Children's Medical Center from October 2019 to May 2022 were enrolled in this study. Their clinical data including general conditions, clinical manifestations, laboratory and imaging examinations, endoscopic procedures and outcomes were retrospectively analyzed. Results: Among the 8 children, 4 were males and 4 females. The diagnosis was confirmed at the age of 6-20 months; the age of onset was 0-12 months and the course of disease was 6-18 months. The main clinical manifestations were recurrent non-biliary vomiting, abdominal distension and malnutrition. One case complicated with refractory hyponatremia was first diagnosed with atypical congenital adrenal hyperplasia in the endocrinology department. After treatment with hydrocortisone, the blood sodium returned to normal, but vomiting was recurrent. One patient underwent laparoscopic rhomboid duodenal anastomosis in another hospital but had recurred vomiting after the operation, who was diagnosed with double duodenal diaphragm under endoscope. No other malformations were found in all the 8 cases. The duodenal diaphragm was located in the descending part of the duodenum, and the duodenal papilla was located below the diaphragm in all the 8 cases. Three cases had the diaphragm dilated by balloon to explore the diaphragm opening range before diaphragm incision; the other 5 had diaphragm incision performed after probing the diaphragm opening with guide wire. All the 8 cases were successfully treated by endoscopic incision of duodenal diaphragm, with the operation time of 12-30 minutes. There were no complications such as intestinal perforation, active bleeding or duodenal papilla injury. At one month of follow-up, their weight increased by 0.4-1.5 kg, with an increase of 5%-20%. Within the postoperative follow-up period of 2-20 months, all the 8 children had duodenal obstruction relieved, without vomiting or abdominal distension, and all resumed normal feeding. Gastroscopy reviewed at 2-3 months after the operation in 3 cases found no deformation of the duodenal bulbar cavity, and the mucosa of the incision was smooth, with a duodenal diameter of 6-7 mm. Conclusion: Endoscopic diaphragm incision is safe, effective and less invasive in pediatric congenital duodenal diaphragm, with favorable clinical applicability.

Blending control method of lower limb exoskeleton toward tripping-free stair climbing. ISA TRANSACTIONS 2022; 131:610-627.

Abstract
Tripping frequently occurs when an individual climbs the stairs with improper foot clearance. Among older adults, falling down the stairs accounts for over 10% of accidental deaths. This paper proposes an exoskeleton control method that blends human-dominant and exoskeleton-dominant control to prevent tripping. The blending controller not only allows the exoskeleton to track the pilot's movements and provide power assistance during regular walking, but also allows the exoskeleton to help the pilot avoid dangers in some cases. An online path planning method is used to generate a safe trajectory in the exoskeleton-dominant mode to help the pilot correct their running trajectory. The controller provides the pilot with adjustment spaces to adapt to sudden changes in the motion mode and enable active self-regulation. The simulations verified the effectiveness of the proposed blending method. Experiments showed that the robot should be involved in the pilot's movements when the foot clearance exceed the safety threshold to prevent tripping.

Abstract
In order to explore the application of "patient and public involvement" (PPI) in acupuncture clinical research, the connotation, reporting standards and research status of PPI at home and abroad are collated, and the key problems of PPI encountered in acupuncture clinical research are deeply considered and summarized. It is suggested that the short-form checklist of the Guidance for Reporting Involvement of Patients and the Public (GRIPP) of the 2nd edition should be applied to acupuncture clinical research. PPI provides a new perspective for acupuncture clinical research. It is beneficial for each stage of research, contributes to the improvement of acupuncture medical service mode and increases the success rate and cost-effectiveness of research so that the innovation and development of acupuncture science can be promoted.

Abstract
Objective: To investigate the application value of household dynamic monitoring of exhaled nitric oxide (FeNO) and pulmonary ventilation function in daily management of asthma. Methods: A total of 22 untreated patients with uncontrolled asthma who visited the Respiratory Disease Clinic of China-Japan Friendship Hospital from October 2019 to December 2020 were enrolled. Demographic characteristics, asthma history, comorbidities, asthma control test (ACT), and mini-asthma quality of life questionnaire (mini-AQLQ) were collected through face-to-face surveys. FeNO, pulmonary ventilation function, sputum eosinophil ratio and blood eosinophil count before treatment were collected through medical records. During the treatment of inhaled corticosteroids (ICS), the subjects were monitored at home for 4 weeks by FeNO analyzer and mobile electronic vital capacity at fixed time in the morning and evening. After the treatment, the above indicators were measured again to evaluate the treatment effect. Diurnal and dynamic changes of FeNO and pulmonary ventilation function monitored at home during treatment were analyzed. Results: The age of the subjects was (40±14) years, and 14 cases were female. After 4 weeks of ICS treatment, ACT score, mini-AQLQ score, forced expiratory volume at 1 second (FEV1, L) and FEV1/forced vital capacity (FVC, %) were 23±2, 5.49±1.04, 2.89±0.60 and 72.2±7.8, respectively, higher than before treatment [16±4, 4.06±0.95, 2.47±0.76 and 66.4±14.3, respectively]. FeNO [ppb (part per billion)], sputum eosinophil percentage (%) and blood eosinophil levels (×106/L) [M (Q1, Q3)] were 27 (18, 47), 2.8 (1.0, 14.0) and 255 (188, 280), respectively, lower than before treatment [80 (56, 117), 25.8 (15.0, 59.6) and 380 (283, 658)] (all P values<0.05). The level of FeNO in the morning was higher than that in the evening 2 weeks before routine monitoring (P=0.028), and no statistical difference was found in pulmonary ventilation function between day and night (P>0.05). The curve fitting of daily monitoring of FeNO and lung ventilation function showed that FeNO and lung ventilation function were gradually improved, and the effective time of treatment determined by FeNO was 3.5 (3.0, 5.3) d, which was earlier than all lung ventilation function indicators (all P values<0.05). The maximum action time of FeNO was (14.5±2.2) d, which was earlier than that of FEV1 (20.7±2.8) d (all P values<0.05), but there was no statistically difference between the maximum effect time determined by other lung ventilation function indicators (all P values>0.05). Conclusion: Household dynamic daily monitoring of FeNO and pulmonary ventilation function can be used to assess the response to ICS treatment, with FeNO being the more sensitive indicator.

Abstract
Objective: To analyze the clinical features, treatment and prognosis of solitary rectal ulcer syndrome (SRUS) in children. Methods: The clinical data of 7 children who were diagnosed with SRUS in Department of Gastroenterology in Guangzhou Women and Children' Medical Center from January 2019 to December 2021 were retrospectively analyzed. The clinical data including general demographics, clinical presentations, endoscopic and histologic features, treatment and outcome were extracted from hospital medical records. Results: The 7 patients were all males, and the age of onset was 6-12 years. The course before diagnosis was 2-36 months. The most common symptom was rectal bleeding (6 cases) and most common findings at initial colonoscopy were ulcer in 3 cases and protuberance in 4 cases, both located only in rectum. The intestinal histopathology of 5 cases showed characteristic fibromuscular obliteration of lamina propria. Five children were treated with mesalamine granules or suppositories, and 2 cases underwent local excision. The follow-up lasted for 5-24 months and found symptoms relieved in 5 cases, improved in 1 case, and no remission in 1 case. Colonoscopy after the treatment was performed in 5 children, among whom 2 cases achieved mucosal healing. Conclusions: SRUS in children is mainly presented with rectal bleeding, and has characteristic histological change of ulcer and protuberance in endoscopy. Pathology is crucial for diagnosis and differential diagnosis. Both the medical and surgical treatment are effective for SRUS.

Abstract
IMPORTANCE Renal colic is described as one of the worst types of pain, and effective analgesia in the shortest possible time is of paramount importance. OBJECTIVES To examine whether acupuncture, as an adjunctive therapy to analgesics, could accelerate pain relief in patients with acute renal colic. DESIGN, SETTING, AND PARTICIPANTS This single-center, sham-controlled, randomized clinical trial was conducted in an emergency department in China between March 2020 and September 2020. Participants with acute renal colic (visual analog scale [VAS] score ≥4) due to urolithiasis were recruited. Data were analyzed from October 2020 to January 2022. INTERVENTIONS After diagnosis and randomization, all patients received 50 mg/2 mL of diclofenac sodium intramuscular injection immediately followed by 30-minute acupuncture or sham acupuncture. MAIN OUTCOMES AND MEASURES The primary outcome was the response rate at 10 minutes after needle manipulation, which was defined as the proportion of participants whose VAS score decreased by at least 50% from baseline. Secondary outcomes included response rates at 0, 5, 15, 20, 30, 45, and 60 minutes, rescue analgesia, and adverse events. RESULTS A total of 115 participants were screened and 80 participants (66 men [82.5%]; mean [SD] age, 45.8 [13.8] years) were enrolled, consisting of 40 per group. The response rates at 10 minutes were 77.5% (31 of 40) and 10.0% (4 of 40) in the acupuncture and sham acupuncture groups, respectively. The between-group differences were 67.5% (95% CI, 51.5% to 83.4%; P < .001). The response rates of acupuncture were also significantly higher than sham acupuncture at 0, 5, 15, 20 and 30 minutes, whereas no significant difference was detected at 45 and 60 minutes. However, there was no difference between the 2 groups in rescue analgesia rate (difference 2.5%; 95% CI -8.8% to 13.2%; P > .99). No adverse events occurred during the trial. CONCLUSIONS AND RELEVANCE These findings suggest that acupuncture plus intramuscular injection of diclofenac is safe and provides fast and substantial pain relief for patients with renal colic compared with sham acupuncture in the emergency setting. However, no difference in rescue analgesia was found, possibly because of the ceiling effect caused by subsequent but robust analgesia of diclofenac. Acupuncture can be considered an optional adjunctive therapy in relieving acute renal colic. TRIAL REGISTRATION Chinese Clinical Trial Registry: ChiCTR1900025202.

Abstract
INTRODUCTION Hypertension is a common risk factor for cardiovascular disease. Transcutaneous electrical acupoint stimulation (TEAS) may be effective for hypertension, but the evidence remains limited. The aim of this study is to evaluate the effectiveness and safety of the smart phone-based TEAS as adjunctive therapy for hypertension. METHODS AND ANALYSIS This study is a 52-week cluster randomised controlled trial with 1600 hypertension patients in 32 community health service centres. Patients who meet the inclusion criteria will be randomised into usual care group or TEAS group in a 1:1 ratio. All patients will be provided with usual care as recommended by the guidelines. In addition to this, patients in the TEAS group will receive non-invasive acupoint electrical stimulation for 30 min at home, 4 times weekly for 12 weeks. The primary outcome will be the mean difference in the changes in office systolic blood pressure from baseline to 12 weeks between TEAS and usual care groups. Secondary outcomes will include the change of mean diastolic blood pressure, proportion of patients with controlled blood pressure (blood pressure <140/90 mm Hg), proportion of patients taking antihypertensive drugs, change in number of antihypertensive drugs and changes in 12-item Short-Form. Tertiary outcomes will include change in body mass index, change in waist circumference, physical activity and medication adherence. Safety outcomes will be any serious adverse events and clinical events. ETHICS AND DISSEMINATION This study has been approved by ethics committee of Beijing University of Chinese Medicine (No. 2020BZHYLL0104). Written informed consent will be obtained from all patients before randomisation. Trial results will be disseminated in peer-reviewed publications. TRIAL REGISTRATION NUMBER ChiCTR2000039400.

Abstract
Objective: To screen and perform preliminary clinical validation of biomarkers of activity based on positron emission tomography/computed tomography (PET-CT) and transcriptomics in sputum-negative pulmonary tuberculosis lesion tissue. Methods: Nine patients with sputum-negative pulmonary tuberculosis treated surgically at the Shanghai Public Health Clinical Center for Thoracic Surgery from January 1, 2017 to December 31, 2019 were retrospectively collected as the discovery group, including four males and five females, aged 20-57 years (mean 36 years). All of the patients underwent PET-CT scanning before surgery, and the resected specimens were postoperatively classified according to preoperative PET-CT. The resected specimens were divided into areas with increased fluorodeoxyglucose (FDG) metabolism (SUVmax>3) and areas with normal FDG metabolism (SUVmax ≤ 3) according to the preoperative PET-CT performance. After sample processing, total RNA was extracted from the tissues of different regions, and then whole gene transcriptome sequencing was performed. Bioinformatics analysis of the two sets of data was performed to discover the expression profiles of the differences in whole gene transcriptome data between the two regions and to screen for candidate biomarkers. Eighty patients with sputum-negative pulmonary tuberculosis admitted to Shanghai Public Health Clinical Center from January 1, 2019 to January 1, 2021 were retrospectively collected as the validation group, including 37 males and 43 females, aged 20-62 years, with an average age of 39 years. The validation group was divided into a group with increased SUV (n=40) and a group without lesions on CT imaging (n=40). Enzyme-linked immunosorbent assay (ELISA) was used to determine the protein levels of candidate biomarkers in the peripheral plasma of patients. The effect of biomarkers was assessed using subject operating characteristic (ROC) curves. Student's t-test was used to determine whether the difference in protein levels between the two groups was statistically significant. Results: Bioinformatics analysis revealed that the expression levels of C1QB, CCL19, CCL5 and HLA-DMB correlated with the metabolic activity of sputum-negative tuberculosis lesion tissue. Further screening and validation by the validation group confirmed that the difference in C1QB protein levels in the peripheral plasma of patients was statistically significant between the group with increased SUV and the group without lesions on CT imaging [(3.55±0.34) mg/L vs. (2.75±0.21) mg/L, t=4.12, P<0.001]. And the ROC curve showed that the area under the curve for C1QB protein levels was 0.731, which had potential clinical value. Conclusion: The C1QB protein level can be used to assess the activity of lesions in patients with sputum-negative tuberculosis and is a potential biomarker.

Abstract
BACKGROUND Chronic Sciatica is a disabling condition causing considerable medical, social and financial implications. Currently, there is no recognised long-term effective treatment to alleviate sciatica. Acupuncture has been widely used for treating chronic pains with persistent analgesic effects. We aim to evaluate the efficacy and safety of acupuncture for chronic sciatica with follow-up in 52 weeks. METHODS AND ANALYSIS This is a multicenter randomised sham-controlled trial. A total of 216 patients with chronic sciatica will be enrolled and randomly assigned to the acupuncture or sham acupuncture group. There will be 10 treatment sessions applied in 4 weeks with frequency decreased over time. Patients will complete follow-ups during 52 weeks. The primary outcomes are changes in leg pain intensity and disability from baseline to week 4. Secondary outcomes include back pain intensity, frequency and bothersomeness, quality of life, and global perceived effect. Adverse events will be recorded in detail. ETHICS AND DISSEMINATION Ethical approval of this trial was granted from the ethics committee of Beijing University of Chinese Medicine and all study centres (No. 2020BZYLL0803). Written informed consent will be obtained from enrolled patients. Trial results will be disseminated in peer-reviewed publications. TRIAL REGISTRATION NUMBER ChiCTR2100044585 (Chinese Clinical Trial Registry, http://www.chictr.org.cn, registered on 24 March 2021); preresults.

Abstract
OBJECTIVE To analyze the main factors affecting the positive results of acupuncture for chronic pain in English literature of randomized controlled trial (RCT), in order to provide reference for the design of acupuncture clinical research. METHODS The RCTs of acupuncture for chronic pain published before March 26, 2020 were searched in PubMed, EMbase and Cochrane Library by computer. A total of 21 factors were analyzed by single-factor analysis, and the factors with statistically significant difference were selected for multivariate Logistic regression analysis. RESULTS A total of 69 RCTs were included, including 47 RCTs (68.12%) with positive results and 22 RCTs (31.88%) with non-positive results. The multivariate Logistic regression analysis was performed with the three screened factors (publication year, treatment frequency and intervention form) selected by single-factor analysis, and the results showed that the positive results were related to the frequency of acupuncture treatment. The positive rate of RCT with frequency≥2 times a week was 3.24 times of that with frequency<2 times a week (OR=3.24, 95%CI =[1.07,9.83], P<0.05). CONCLUSION Acupuncture frequency may be the main factor affecting the positive results of RCT in English literature of acupuncture for chronic pain. More researches are needed in the future to explore the influence of acupuncture frequency on the curative effect.

Abstract
Objective: To construct a novel prognostic nomogram model based on more comprehensive variables for patients with small-cell lung cancer (SCLC). Methods: The data of 722 patients with SCLC confirmed by pathology in Affiliated Cancer Hospital of Shanxi Medical University from January 2015 to December 2018 were retrospectively analyzed [including 592 males and 130 females, aged from 23 to 82(61±9) years]. A random seed count of 133 was used to divide those patients into training set (n=422) and validation set (n=300). Kaplan-Meier was used for survival curves analysis and univariate Log-rank test was used for evaluating the influence of clinical variables on the prognosis of sclc, variables with P<0.05 in univariate analysis were included in a multivariate Cox regression model. The nomogram was constructed based on the variables which P<0.05 in multivariate analysis. Receiver operating characteristic (ROC) curve, calibration by Integrated Brier score (IBS) and clinical net benefit by decision curve analysis (DCA) were used to evaluate model discriminative power, prediction error value, and clinical net benefit, and compared with the American Joint Committee on Cancer 8th TNM. Results: Male, abnormal monocyte (MON) counts, abnormal neuron specific enolase (NSE), abnormal cytokeratin 19 fragment (Cyfra211), M1a stage, M1b stage, M1c stage, radiotherapy (RT), chemotherapy ≥4 cycles and prophylactic cranial irradiation (PCI) were prognostic factors for SCLC[HR(95%CI)=1.39(1.00-1.92), 1.29(1.02-1.63), 1.41(1.11-1.80), 2.02(1.48-2.76), 1.09(0.77-1.55), 1.44(0.94-2.22), 2.01(1.49-2.71), 0.75(0.57-0.98), 0.40(0.31-0.51)and 0.42(0.26-0.68), respectively, all P<0.05]. The area under ROC curve (AUC) of the nomogram in training set and validation set were 0.814(95%CI: 0.765-0.862)and 0.787 (95%CI: 0.725-0.849), which were higher than TNM [0.616(95%CI: 0.558-0.674) and 0.648(95%CI: 0.581-0.715)].The calibration curve showed a good correlation between the nomogram prediction and actual observation for the 2-year overall survival (OS). IBS indicted a lower prediction error rate (training set: 0.132 vs 0.169; validation set: 0.138 vs 0.169). DCA showed a wider threshold range than TNM (training set: 0.01-0.96 vs 0.01-0.85, validation set: 0.01-0.94 vs 0.01-0.86) and a greater improvement of the clinical net benefit (in training set the nomogram had a greater clinical benefit than TNM in the range of 0.19-0.96, and remained in validation set in the range of 0.19-0.94). Conclusion: The established nomogram model for predicting 2-year OS in patients with SCLC based on 8 variables, including gender, MON, NSE, Cyfra211, M stage, RT, CT cycles and PCI can be used for an more accurately prognosis prediction and reference for therapeutic regimen selection.

Abstract
Objective: To explore the effect of vestibular rehabilitation and to identify factors that can affect rehabilitation outcomes. Methods: From December 2018 to October 2020, patients who underwent vestibular rehabilitation in the Eye, Ear, Nose and Throat Hospital of Fudan University were prospectively followed up. A battery of vestibular function examinations and psychological status evaluations were applied before and after rehabilitation initiation. The main outcomes were vertigo/dizziness and unsteadiness, measured by visual analogue scale (VAS); Secondary outcomes were daily activities and participation, assessed by vestibular activities and participation measure (VAP). Paired t-test was used to compare the effects before and after rehabilitation. Binary logistic regressions were applied to analyze the influencing factors of rehabilitation outcomes. Results: A total sample of 171 patients was followed up regularly with a median time of 11 months. Of the 171 patients evaluated, 72 were males and 99 were females; age ranged from 10 to 89 years old with a median age of 55 years old. At 6-month follow-up, the difference of VAS score of vertigo/dizziness and unsteadiness pre-post rehabilitation was 1.79±1.80 and 1.56±1.76, respectively; The difference of activity and participation domain of VAP score was 2.51±13 and 1.27±3.75, respectively. All differences pre-post rehabilitation exhibited statistically significant with P values<0.01. Regression analysis demonstrated that the length of symptom onset was a significant predictor of poor balance recovery (OR=6.52; 95%CI:2.10, 20.27). Visual dependence (OR=5.44; 95%CI: 1.38, 21.47) and suspectable anxiety (OR=6.45; 95%CI: 1.49, 28.30) were identified as risk factors for poor recovery of vertigo/dizziness. Conclusions: Vestibular rehabilitation effectively reduces dizziness, promotes balance, and improves the function of daily activities. Time from the onset, visual dependence and suspectable anxiety are the main factors hindering a desirable rehabilitation outcome.

Abstract
Objective: To explore the effect of human bone marrow mesenchymal stem cells(MSC) on the steroid resistance of human airway epithelial cells. Methods: Ovalbumin (OVA)/lipopolysaccharide (LPS) were used to construct steroid resistant BEAS-2B cells, which were then co-cultured with MSC. Groups were set as follows: blank group, model group, Glucocorticoid group, MSC group, MSC+Glucocorticoid group (MSC+bud group). The expression of interleukin (IL)-8 in the cell supernatant was detected by enzyme-linked immunosorbent assay (ELISA); the expression of reactive oxygen species (ROS) in the cells was detected by flow cytometry; the expression of glucocorticoid receptor α (GRα) and histone deacetylase 2 (HDAC2) protein in the cell was detected by Western blotting; and the expression of GRα and HDAC2 mRNA was detected by reverse transcription-polymerase chain reaction (RTPCR). Results: The expression level of IL-8 in the MSC group was significantly lower than that in the Glucocorticoid group (31.7±0.7 vs. 49.8±3.6, P<0.01). The expression of ROS in the MSC group was significantly lower than that in the Glucocorticoid group (2754±154 vs.4624±228, P<0.05). The expression level of HDAC2 mRNA in the MSC group was significantly higher than that in the Glucocorticoid group(1.749±0.005 vs. 1.283±0.098, P<0.05). The expression level of GRα mRNA in the MSC group was significantly higher than that in the Glucocorticoid group (1.623±0.079 vs.1.047±0.220, P<0.01). The expression of HDAC2 protein in the MSC group was significantly higher than that in the Glucocorticoid group (1.067±0.100 vs. 0.620±0.083, P<0.01). The expression of GRα protein in the MSC group was significantly higher than that in the Glucocorticoid group (0.834±0.053 vs. 0.579±0.017, P<0.01). ROS was positively correlated with the IL-8 expression (r=0.796, P<0.01) and negatively correlated with the HDAC2 and GRα mRNA expression (r=-0.893 3, P<0.01; r=0.931 4, P<0.01, respectively), as well as the HDAC2 and GRα Protein expression (r=-0.929 5, P<0.01;r=-0.864 3, P<0.01, respectively). Conclusions: Human MSC can improve steroid resistance of airway epithelial cells in an exocrine manner. The mechanism may be related to the down-regulation of ROS and up-regulation of HDAC2, which lead to GRα overexpression. In addition, MSC may improve the steroid resistance by reducing the expression of IL-8.

Abstract
Objective: To explore the characteristics of dynamic balance during the onset of benign paroxysmal positional vertigo (BPPV) and its prediction of residual symptoms after successful repositioning. Methods: From January 2018 to August 2019, patients diagnosed with unilateral posterior semicircular canal or horizontal semicircular canal BPPV were consecutively enrolled from five otolaryngology clinics in Shanghai. The dynamic balance function was measured by sensory organization test (SOT) before repositioning maneuver, and the residual symptoms and its duration were followed up from one week to up to three months. Results: A total of 260 patients were recruited. After excluding 17 cases, 243 cases were successfully followed up including 89 males and 154 females, with an average age of (52.9±13.0) years. There were 175 cases of posterior semicircular BPPV, 61 cases of horizontal semicircular BPPV and 7 cases of canal conversion (from horizontal to posterior semicircular). Among 243 patients, 118 cases reported residual symptoms, with an incidence of 48.6%. The results of SOT showed that 58.0%(141/243) of the patients had abnormal vestibular input and 41.6%(101/243) were categorized as "near falls". With respect to the detailed residual symptoms, 47 cases (39.8%) reported unsteadiness or floating, 35 cases (29.7%) had fogginess/heaviness feeling, 22 cases (18.6%) had transient dizzy while head moving, and 15 cases (12.7%) reported that the symptom was too subtle to describe. Compared with the group without residual symptoms, the group with residual symptoms had more abnormal vestibular input(χ²=67.25, P<0.001) and near falls(χ²=74.78, P<0.001) as identified by SOT test. Cox proportional hazards regression failed to reveal any SOT results having significantly impact on the duration of residual symptoms [abnormal vestibular input (HR= 0.93, 95%CI: 0.48, 1.80), and near falls (HR= 0.90, 95%CI: 0.56, 1.46)]. Kaplan-Meier survival analysis showed that there was no significant difference in the duration of residual symptoms among patients with different SOT manifestations [Log rank (Mantel-Cox) test, P>0.05]. Conclusions: The impaired dynamic balance during the onset of BPPV is characterized by "abnormal vestibular input". The residual symptoms are mainly characterized by unsteadiness or floating feeling. The defect of dynamic balance function is a predictor of the residual symptoms after successful repositioning, but not for the duration of such symptoms.

Abstract
Objective: To analyze the current status, trend and predictors of thromboembolism risk assessment in patients hospitalized with non-valvular atrial fibrillation (NVAF) in tertiary hospitals in China. Methods: The study was based on data from the Improving Care for Cardiovascular disease in China (CCC)-Atrial Fibrillation (AF) project. About 10% of the tertiary hospitals in each geographic-economic stratum were recruited. Participating hospitals reported the first 10 to 20 patients with a discharge diagnosis of atrial fibrillation monthly. From February 2015 to December 2019, a total of 49 104 NVAF patients from 151 tertiary hospitals in 30 provinces, municipalities and autonomous regions were enrolled. Clinical data of the patients was collected. The proportion of NVAF patients receiving thromboembolism risk assessment, variations in the proportion between different hospitals, the time trend of the application of thromboembolism risk assessment, and the predictors of the application of thromboembolism risk assessment were analyzed. Results: The age of the NVAF patients was (68.7±12.1) years, 27 709 patients (56.4%) were male. Only 17 251 patients (35.1%) received thromboembolism risk assessment. The proportion varied substantially between hospitals with the lowest value of 0 and the highest value of 100%. Among the hospitals, which enrolled more than 30 patients, no patients received thromboembolism risk assessment in 18.4% (26/141) of the hospitals, more than 50% of the patients received thromboembolism risk assessment in 21.3% (30/141) of the hospitals, and all the patients received thromboembolism risk assessment in only 1 hospital. The proportion of NVAF patients receiving thromboembolism risk assessment was 16.2% (220/1 362) in the first quarter of 2015, and significantly increased to 67.1% (1 054/1 572) in the last quarter of 2019 (P<0.001). Patients' characteristics were associated with the application of thromboembolism risk assessment. The odds of receiving thromboembolism risk assessment was lower in male patients compared to female patients(OR=0.94,95%CI 0.89-0.99), lower in patients with acute coronary syndrome or other cardiovascular diseases compared to those with AF as the primary admission reason (OR=0.59, 95%CI 0.55-0.63, OR=0.52, 95%CI 0.45-0.61, respectively), and lower in patients with paroxysmal, persistent and long-standing/permanent AF compared to those with first detected AF (OR=0.62, 95%CI 0.57-0.67, OR=0.72, 95%CI 0.66-0.79, OR=0.57, 95%CI 0.52-0.64, respectively). The odds was higher in patients with a history of hypertension, heart failure, stroke/TIA, and previous anticoagulant therapy compared to those without the above conditions (OR=1.17, 95%CI 1.11-1.23, OR=1.18, 95%CI 1.07-1.30, OR=1.17, 95%CI 1.08-1.27, OR=1.28, 95%CI 1.19-1.37, respectively) (P all<0.05). Conclusion: Thromboembolism risk assessment was underused in patients hospitalized with NVAF in tertiary hospitals in China, and there were substantial variations between hospitals in the application of thromboembolism risk assessment. The application of thromboembolism risk assessment in tertiary hospitals has been improved in recent years, but there is still plenty of room for future improvement. Patients' characteristics could affect the application of thromboembolism risk assessment in China.

New α-Emitting Isotope ^{214}U and Abnormal Enhancement of α-Particle Clustering in Lightest Uranium Isotopes. PHYSICAL REVIEW LETTERS 2021; 126:152502.

Abstract
A new α-emitting isotope ^{214}U, produced by the fusion-evaporation reaction ^{182}W(^{36}Ar,4n)^{214}U, was identified by employing the gas-filled recoil separator SHANS and the recoil-α correlation technique. More precise α-decay properties of even-even nuclei ^{216,218}U were also measured in the reactions of ^{40}Ar, ^{40}Ca beams with ^{180,182,184}W targets. By combining the experimental data, improved α-decay reduced widths δ^{2} for the even-even Po-Pu nuclei in the vicinity of the magic neutron number N=126 are deduced. Their systematic trends are discussed in terms of the N_{p}N_{n} scheme in order to study the influence of proton-neutron interaction on α decay in this region of nuclei. It is strikingly found that the reduced widths of ^{214,216}U are significantly enhanced by a factor of two as compared with the N_{p}N_{n} systematics for the 84≤Z≤90 and N<126 even-even nuclei. The abnormal enhancement is interpreted by the strong monopole interaction between the valence protons and neutrons occupying the π1f_{7/2} and ν1f_{5/2} spin-orbit partner orbits, which is supported by the large-scale shell model calculation.

Abstract
Objective: To compare the effects of different intervention strategies for the management of residual dizziness following successful canalith repositioning procedure (CRP) in patients with benign paroxysmal positional vertigo (BPPV). Methods: A total of 129 BPPV patients with residual dizziness following successful CRP were recruited during January 2019 and July 2019. They were randomly assigned into three groups with 43 cases in each group: the vestibular rehabilitation group received rehabilitation training for four weeks; betahistine group was given orally 12 mg betahistine three times a day for four weeks; and the control group had no specific treatment. The primary outcomes were daily activities and social participation assessed by the Vestibular Activities and Participation measure (VAP). Secondary outcomes includedbalance function assessed by sensory organization test (SOT) and the duration of residual symptoms. Stata15.0 software was used for statistical analysis. Results: The scores of VAP in the three groups decreased over time, but a more significant decrease was found in vestibular rehabilitation group. Further paired comparison showed that the difference between the vestibular rehabilitation group and the control group was of statistical significance (B=-3.88, χ2=18.29, P<0.01), while the difference between the betahistine group and the control group was not statistically significant (B=-0.96, χ2=1.16, P=0.28). The balance function of the three groups showed a trend of recovery over time, with no significant differences between groups (χ2=1.37, df=2, P>0.05). The median duration of residual dizziness for both vestibular rehabilitation and betahistine groups was 14 days, while that of control group was 19 days, with no significant difference between three groups[Log-rank (Mantel-Cox) test; χ2=1.82, df=2, P=0.40]. Conclusion: Vestibular rehabilitation can significantly improve the daily activities and social participation function in BPPV patients with residual symptoms following successful CRP, but its effects on shortening the duration of residual symptoms and promoting the recovery of balance function remain uncertain.

[PMID: 33413569 PMCID: PMC7792186 DOI: 10.1186/s13063-020-04967-y] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/18/2020] [Accepted: 12/11/2020] [Indexed: 12/17/2022] Open
Abstract
Background Atrial fibrillation (AF) is a common arrhythmia, which is closely related to cardiovascular morbidity and mortality. Although acupuncture is used in the treatment of AF, the evidence is insufficient. The objective of this pilot trial is to evaluate the feasibility, preliminary efficacy, and safety of acupuncture in reducing AF burden for persistent AF after catheter ablation (CA). Methods and design This will be a multi-center, 3-arm, pilot randomized controlled trial in China. Sixty patients in total will be randomly assigned to the specific acupoints group, the non-specific acupoints group, or the non-acupoints group in a 1:1:1 ratio. The whole study period is 6 months, including a 3-month treatment period and a 3-month follow-up period. All patients will receive 18 sessions of acupuncture over 12 weeks after CA and appropriate post-ablation routine treatment. The primary outcome is AF burden at 6 months after CA measured by electrocardiography patch that can carry out a 7-day continuous ambulatory electrocardiographic monitoring. The secondary outcomes include AF burden at 3 months after CA, recurrence of AF, quality of life, etc. The adverse events will also be recorded. Discussion This pilot study will contribute to evaluating the feasibility, preliminary efficacy, and safety of acupuncture in reducing AF burden for persistent AF after CA. The results will be used for the sample size calculation of a subsequent large-scale trial. Trial registration Chinese Clinical Trial Registry ChiCTR2000030576. Registered on 7 March 2020.

[Evaluation of the effectiveness of bronchial thermoplasty in patients with severe asthma in the real world two years after bronchial thermoplasty treatment]. ZHONGHUA YI XUE ZA ZHI 2020; 100:1730-1735. [PMID: 32536095 DOI: 10.3760/cma.j.cn112137-20200211-00245] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Subscribe] [Scholar Register] [Indexed: 11/05/2022]
Abstract
Objective: To assess the effectiveness of bronchial thermoplasty (BT) in "real-world" patients with severe asthma at 2 years post therapy. Method: Outcomes of 70 patients with severe asthma undergoing bronchial thermoplasty from March 2014 to November 2017 in China-Japan Friendship Hospital were retrospectively analyzed two years post therapy. The scores of Asthma Control Test (ACT) and Mini Asthma Quality of Life Questionnaire (mini-AQLQ), the number of severe exacerbations, emergency department visits and hospitalizations for asthma symptoms in the past year, indicators of pulmonary function including forced expiratory volume in one second (FEV(1)), FEV(1) as a percentage of predicted value (FEV(1)%pred) and FEV(1)/forced vital capacity (FEV(1)/FVC), maintenance asthma medications, the cost of asthma drugs and the total annual cost of asthma treatment were evaluated and analyzed before and 2 years after BT therapy, and the subjective assessment about effectiveness of BT were given by the patients. Results: Before and 2 years after BT, the numbers of subjects suffering severe exacerbations in the past year were 70 (100%) and 37 (52.9%), and the numbers of total severe exacerbations were 575 and 162 respectively. The numbers of patients having emergency department visits due to asthma exacerbation were 46 (65.7%) and 9 (12.9%), and the numbers of emergency department visits were 186 and 19 respectively. The numbers of patients hospitalized due to asthma exacerbation were 43 (61.4%) and 16 (22.9%), and the numbers of total hospitalizations were 124 and 24, respectively. The rate of severe exacerbation, emergency department visit and hospitalization were significantly reduced two years after the treatment by 71.9%, 88.9% and 83.3% (all P<0.001). The scores of ACT and mini-AQLQ were significantly increased [22 (21, 24) vs 17 (13, 19), (5.57±0.89) vs (3.83±0.92); both P<0.001]. Two years after BT, 4 patients (5.7%) were weaned off inhaled corticosteroids (ICS) and long-acting β(2)-agonist (LABA), while 14 patients (37.8%) were weaned off oral corticosteroid (OCS), with daily dose of ICS and OCS significantly decreased (both P<0.05). The proportion of patients treated with montelukast sodium and theophylline was also significantly reduced after BT (40.0% vs 81.4%, 27.1% vs 71.4%; both P<0.001). In addition, the indicator of FEV(1), FEV(1)%pred and FEV(1)/FVC ratio were all greatly improved two years after the treatment [2.27 (1.84, 2.82) vs 2.10 (1.70, 2.61) L, (76.8±19.5)% vs (72.5±19.8)%, (66.3±13.6)% vs (63.8±13.0)%; all P<0.05]. The annual cost for asthma drug and asthma treatment after BT were significantly decreased (P<0.001). Fifty-nine patients (84.3%) subjectively assessed the treatment as effective. Conclusion: The bronchial thermoplasty in "real-world" patients with severe asthma could significantly improve the asthma control, lung function and quality of life, and reduce severe exacerbations, emergency department visits and hospitalizations for asthma symptoms, while the maintenance asthma medications, the cost of asthma drugs and the total annual cost of asthma treatment are significantly decreased.

Abstract
Objective: To explore the correlation between dietary N-glycolylneuraminic acid (Neu5Gc) intake and chronic inflammation state of body. Methods: A total of 306 samples of 102 types of food were purchased from a supermarket in Xiamen in September 2019, including grains, meat, poultry, seafood, eggs, beans, dairy products, vegetables and fruits. The content of Neu5Gc in food was determined by liquid chromatography-mass spectrometry. A total of 500 healthy freshmen from Xiamen University were selected by using a simple random sampling method. The food frequency questionnaire was used to investigate the food intake in the past year. The food intake was corrected by 3 consecutive 24-hour recalls, and the amount of Neu5Gc intake was calculated. The concentration of anti-Neu5Gc antibody, C-reactive protein (CRP) and interleukin-6 (IL-6) in serum was detected. Spearman correlation analysis was used to explore the correlation between Neu5Gc intake and anti-Neu5Gc antibody, CRP and IL-6 levels. Results: Neu5Gc was mainly found in red meat and liquid dairy products. The contents of Neu5Gc in beef, lamb and pork were (30.32±2.84), (20.39±4.73) and (5.58±1.04) mg/kg, respectively, and in liquid milk and yogurt were (10.87±1.54) and (6.91±0.24) mg/L, respectively. The M (P25, P75) intake of Neu5Gc for all participants was 4.62 (2.20, 8.60) mg/d. The M(P25, P75) intake of Neu5Gc for males about 6.60(2.83, 10.20) was higher than that for females about [3.84 (1.84, 6.35) mg/d] (P<0.001). The M (P25, P75) of serum anti-Neu5Gc, CRP and IL-6 levels were 3.07 (2.17, 4.14) μg/ml, 0.37 (0.22, 0.87) mg/ml and 61.82 (12.23, 315.30) pg/ml, respectively. Spearman correlation analysis showed that the intake level of Neu5Gc was positively correlated with serum anti-Neu5Gc antibody, CRP and IL-6 levels, with rs values about 0.222, 0.102 and 0.126, respectively (all P values <0.05). Conclusion: Dietary Neu5Gc intake is mainly from red meat and liquid dairy products, and its intake level is positively correlated with chronic inflammatory state of body.

Abstract
Objective: To explore the value of nucleic acid detection methods in pharyngeal swabs in the etiological diagnosis of Mycoplasma pneumoniae (MP) infection in children. Methods: Four hundred and fifty-four (male 210, female 244) children with pneumonia in Department of Pulmonology, Children's Hospital of Zhejiang University School of Medicine were enrolled from July, 2018 to October, 2018. Pharyngeal swabs and venous blood were obtained on the first or the second day after hospitalization. Fluorescence detection quantitative amplification of DNA, thermostatic amplification of RNA, MP culture and MP-IgM were used to detect MP simultaneously. MP infection is diagnosed if MP culture is positive or the two of the other three methods are positive. Pharyngeal swabs were acquired and detected using fluorescence quantitative amplification of DNA, thermostatic amplification of RNA and MP culture again for children with confirmed MP infection before discharge. The detection rates and quantitative changes of the three methods were compared, and χ(2) test was used for comparison among groups. Results: A total of 454 hospitalized children with pneumonia were included in this study. The detection rates of fluorescence quantitative amplification of DNA, thermostatic amplification of RNA, MP culture and MP-IgM IgM were 43.6% (198/454), 43.2% (196/454), 40.0% (180/454) and 30.6% (139/454) respectively. The difference of detection rates of the four methods was statistically significant (χ(2)=20.8, P<0.05),but no significant difference between the detection rates of fluorescence quantitative amplification of DNA and thermostatic amplification of RNA was found (χ(2)=0.018, P=0.900). They both had higher detection rates than MP-IgM or MP culture. MP infection is diagnosed if MP culture is positive or the two of the other three methods are positive, and two hundred and nine children were diagnosed as MP infection. In the second test of MP infection in 209 children before discharge, the positive rate of MP culture was 67.5% (141/209), with 39.4% (13/33) changed from negative to positive, and 27.3% (48/176) changed from positive to negative. The positive rate of thermostatic amplification of RNA was 82.3% (172/209), with 16.2% (31/191) turned from positive to negative, and 66.7% (12/18) turned from negative to positive. The positive rate of fluorescence quantitative amplification of DNA was 67.0% (140/209), with 52.9% (18/34) cases changed from negative to positive, and 30.3% (53/175) cases changed from positive to negative. MP-DNA load decreased in 141 cases (67.5%) and increased in 68 cases (32.5%) in the second test among the positive samples tested by fluorescence quantitative amplification of DNA. The detection rates of the four methods in the non-severe group and the severe group were similar, and the differences among the groups were not statistically significant (all P>0.05). In the second test, the proportion of changing from negative to positive in the severe group was higher than that in the non-severe group, but only the difference in the thermostatic amplification of RNA was statistically significant (P=0.038) and the cases of changing from negative to positive of thermostatic amplification of RNA in the severe group and non-severe group are 7 and 5 respectively. Conclusions: The methods of pharyngeal swab nucleic acid detection have high sensitivity and application value in the etiological diagnosis of acute MP infection in children. The results of fluorescence quantitative amplification of DNA and thermostatic amplification of RNA are highly consistent, and they are both more advantageous than MP-IgM. Repeated testing in the acute phase is helpful to find MP infection children whose first test is negative. The load of MP-DNA did not decrease in some children in the acute stage after antibiotic treatment.

Abstract
Flexible photodetector shows great potential applications in intelligent wearable devices, health monitoring, and biological sensing. In this work, single crystal β-tellurium nanowires were grown on flexible muscovite by molecular beam epitaxy, constructing high-density ordered nanomesh structure. The prepared photodetectors based on tellurium nanomesh exhibit excellent mechanical flexibility, fast response in a broad range from ultraviolet to near-infrared, and good photosensitivity. We found that the flexible photodetectors with Shottky contact drastically suppressed dark current, while the response speed was lowered in comparison to the devices with ohmic contact, as holes would take a long time to tunnel through the Shottky barrier between metal and p-type Te. Moreover, the photoresponse of flexible Shottky photodetectors can be modulated by piezoelectricity of tellurium, and pronounced photocurrent increase after bending many times. Under external stress, polarization charges could tune Shottky barrier height of the metal/tellurium, resulting in variation of photocurrent. This research not only explores the broadband photoresponse and piezoelectric effect of tellurium nanomesh, but also promotes the integration and development of broadband flexible optoelectronic devices.

Abstract
On October 23, 2017, a 52-year-old male patient with 3 recurrences of dermatofibrosarcoma protuberans in the left shoulder and chest was admitted to the Department of Burns and Plastic Surgery of Dali Bai Autonomous Prefecture People's Hospital. Dermatofibrosarcoma protuberans on the skin were completely resected, leaving wound defect of 10 cm×10 cm. The wound was planned to be repaired by the transplantation of right anterolateral thigh perforator free flap. However, the anterolateral thigh perforator branch was absent during flap removal, and only one small perforating branch was found. Moreover, it was difficult to separate. Therefore, this flap cutting was given up. The anteromedial thigh perforator was explored through the same incision, and a thicker perforator was found, which was supplied by an independent iatrogenic artery. The length and diameter of the vascular pedicle matched with the blood vessels in the receiving site. An anteromedial thigh perforator flap (10 cm×10 cm) was cut to repair the defect. The postoperative 9-month follow-up revealed that the color, texture, and thickness of the flap were good, the two-point discrimination distance was 30 mm, and the linear scar remained at the donor site of right thigh.

Abstract
OBJECTIVE To observe the clinical effect of acupuncture at "experienced ten acupoints" for postprandial distress syndrome. METHODS A total of 62 patients with postprandial distress syndrome were randomly divided into an observation group (31 cases, 5 cases dropping off) and a control group (31 cases, 6 cases dropping off ). Acupuncture was applied at Baihui (GV 20), Zhongwan (CV 12), Qihai (CV 6), Tianshu (ST 25), Neiguan (PC 6), Zusanli (ST 36), Gongsun (SP 4), Danzhong (CV 17) in the observation group. In the control group, 6 non-acupoint points were intervened with shallow puncture. The treatment was given 20 min each time, once every other day, 3 times a week for a total of 4 weeks in the two groups. Symptom index of dyspepsia (SID) and Nepean dyspepsia index (NDI) scores were compared before and after treatment, and the efficacy was evaluated in the two groups. RESULTS The effective rate in the observation group was 76.9% (20/26), which was higher than 28.0% in the control group (7/25, P<0.01). After treatment, the SID and NDI scores in the two groups were lower than those before treatment (P<0.01, P<0.05), and the SID and NDI scores in the observation group were lower than those in the control group (P<0.01, P<0.05). CONCLUSION Acupuncture at "experienced ten acupoints" can significantly reduce the symptoms of dyspepsia and improve the quality of life in patients with postprandial distress syndrome.

Abstract
Abstract
Background
Increased body mass index (BMI) is a well-established risk factor for cardiovascular disease, however, patients with elevated BMI comparing to low BMI seem to have better survival, a phenomenon reported as “obesity paradox” which remains as a controversy. We investigated the effect of BMI, including underweight, normoweight, overweight and obese, on cardiac mortality post acute myocardial infarction (AMI).
Methods
This analysis included 3562 AMI patients with documented BMI. The baseline characteristics including clinical and laboratory parameters were collected at hospital admission for AMI. Patients were classified into 4 groups based on BMI values: underweight (BMI <18.5), normoweight (BMI 18.5 to 24.9), overweight (BMI 25 to 29.9) and obese (BMI ≥30). Patients were followed up for a median of 1.9 years. The rate of cardiac death (primary endpoint) was compared among the 4 BMI groups. Cox proportional hazard models were used to adjust for potential confounders.
Results
Of 3562, 110 (3%) were underweight, 1579 (44%) were normoweight, 1493 (42%) were overweight, and 380 (11%) were obese. Compared to the normoweight group, subjects in overweight and obese groups were younger, more men, more hypertension, more likely to receive percutaneous coronary intervention (PCI), and had higher levels of glucose and lipids, but, lower level of N-terminal pro-brain natriuretic peptide (NTproBNP). Subjects in underweight group were older, more women, fewer diabetes, less likely to receive PCI, lower levels of glucose and lipids, but, higher level of NTproBNP and higher rates of left ventricular ejection fraction (LVEF)<50%. Cardiac death over 1.9 years occurred significantly more in the underweight group (30.0%, 10.6%, 7.0% and 5.0% among the 4 groups from underweight to obese, p<0.001 for trend, Figure 1). The Cox proportional hazard model revealed that underweight was an independent predictor of subsequent cardiac death (OR=2.58, 95% CI: 1.52–4.39, p<0.001). Multivariate analysis identified that older age, higher levels of cardiac troponin I (cTnI) and LVEF<50% were independently associated with increased risk of cardiac death. PCI significantly and independently protected AMI patients against cardiac death (OR=0.34, 95% CI: 0.23–0.49, p<0.001).
Conclusions
Patients who were underweight were at greater risk of cardiac death post AMI. In addition, older age, higher levels of cTnI, LVEF<50%, and not receiving PCI also independently predicted cardiac mortality post AMI.

Abstract
Abstract
Objective
To observe the effects of different admission systolic blood pressure (SBP) levels on the in-hospital and long-term prognosis of elderly patients with acute coronary syndrome (ACS).
Methods
This retrospective cohort study included 5812 ACS patients aged 65 and over admitted from January, 2013 to September, 2018. Their blood pressure, medical history and laboratory examinations were recorded. The patients were divided into 5 groups according to the level of admission SBP (<100, 100–119, 120–139, 140–159, and ≥160 mmHg). The main endpoint of this study was cardiac death and all-cause death in hospital and during 6-year follow-up.
Results
Among the participants, the number of patients admitted with SBP <100, 100–119, 120–139, 140–159, and ≥160 mmHg were 143 (2.5%), 1014 (17.4%), 2456 (42.3%), 1607 (27.6%), and 592 (10.2%), respectively. The highest in-hospital cardiac mortality and all-cause mortality rate were found in the group with admission SBP <100 mmHg and the lowest were found in the group with SBP 140–159 mmHg (9.1% vs. 3.2% vs. 1.1% vs. 0.8% vs. 1.5%, P=0.000; 9.8% vs. 3.4% vs. 1.1% vs. 0.8% vs. 1.7%, P=0.000). Kaplan-Meier curve showed that patients with SBP 120–139 mmHg at admission had better prognosis (cardiac mortality: 3.9% vs. 10.9%, 5.6%, 5.1%, and 6.7% respectively, P=0.000; all-cause mortality: 7.6% vs. 14.7%, 9.7%, 9.1%, and 11.0%, respectively, P=0.000). Multivariate analysis showed that admission SBP <120 mmHg or ≥160 mmHg was a independent predictors of follow-up cardiac death (HR 1.747, 95% CI 1.066–2.861, P=0.027; HR 1.496, 95% CI 1.092–2.050, P=0.012; HR 1.630, 95% CI 1.120–2.372, P=0.011) compared with patients admitted with SBP 120–139 mmHg.
In-hospital and 6-year follow-up outcomes of ACS patients ≥65y by admission SBP Admission SBP Level <100mmHg ≥100mmHg and <120mmHg ≥120mmHg and <140mmHg ≥140mmHg and <160mmHg ≥160mmHg P In-hospital (n=143) (n=1014) (n=2456) (n=1607) (n=592) Cardiac mortality, n (%) 13 (9.1) 32 (3.2) 28 (1.1) 13 (0.8) 9 (1.5) 0.000 All-cause mortality, n (%) 14 (9.8) 34 (3.4) 28 (1.1) 13 (0.8) 10 (1.7) 0.000 Follow-up (n=129) (n=980) (n=2428) (n=1594) (n=582) Cardiac mortality, n (%) 14 (10.9) 55 (5.6) 94 (3.9) 81 (5.1) 39 (6.7) 0.000 All-cause mortality, n (%) 19 (14.7) 95 (9.7) 185 (7.6) 144 (9.1) 64 (11.0) 0.000
Kaplan-Meier analyses
Conclusion
In ACS patients ≥65 y, a “J” relationship between admission SBP and cardiac mortality is observed. For ACS patients aged 65 years and over, admission SBP <120 mmHg or ≥160mmHg is a independent risk factor for long-term cardiac death.

Abstract
Objective: To observe the effects of artesunate on airway responsiveness and airway inflammation in asthmatic mice. Methods: Thirty female BALB/c mice aged 6-8 weeks were randomly divided into control group, asthma group and artesunate group. In the asthma group and the artesunate group, the mice were sensitized by intraperitoneal injection of 20 μg of ovalbumin (OVA) and 0.2 ml of aluminum hydroxide suspension (2 mg) on day 0 and 14, respectively, and 1% OVA 10 ml dissolved in sterile phosphate (PBS) buffer was aerosolized for 30 min from the 21st to 28th day. The control group was sensitized with 0.2 ml of 2 mg suspension of aluminum hydroxide on day 0 and 14, and aerosolized by 10 ml of sterile PBS from the 21st to 28th day. Before the challenge, the artesunate group was intraperitoneally injected with 0.2 ml of artesunate. Artesunate was replaced with the same amount of normal saline in the control group and the asthma group. The mice were treated after 24 hours of last stimulation. The airway responsiveness of mice was measured by airway intubation and the changes of airway resistance and compliance were observed. Bronchoalveolar lavage fluid (BALF) was classified by cytology, and pathological changes of left lung tissue were observed and scored. Results: The airway resistance of the three groups increased and the lung compliance decreased with the increase of methacholine (Ach) concentration. The airway resistance and lung compliance of the three groups were different under the same concentration (P<0.05). The airway resistance of the artesunate group at Ach 6.25, 12.5, 25, 50, 100 mg/ml was lower than that of the asthma group at the same concentration [(1.01±0.48) vs (1.30±0.22), (1.06±0.44) vs (1.70±0.31), (1.30±0.64) vs (2.66±0.79), (1.82±0.55) vs (3.38±1.35), (2.49±0.85) vs (4.07±1.34) cmH(2)O·s(-1)·ml(-1)(1 cmH(2)O=0.098 kPa); t=3.862, 7.376, 9.113, 7.051, 6.685, all P<0.05]; the degree of lung compliance decrease at the concentration of Ach 3.125, 6.25, 12.5, 25, 50, 100 mg/ml was lower than that of the asthma group at the same concentration [(3.89±0.55)×10(-2) vs (3.07±0.63)×10(-2), (3.61±0.52)×10(-2) vs (3.04±0.58)×10(-2), (3.48±0.38)×10(-2) vs (2.78±0.57)×10(-2), (3.09±0.52)×10(-2) vs (1.73±0.62)×10(-2), (2.32±0.60)×10(-2) vs (1.29±0.54)×10(-2), (1.87±0.59)×10(-2) vs (1.15±0.44)×10(-2) ml/cmH(2)O; t=-6.295, -4.921, -6.533, -11.135, -8.48, -6.319, all P<0.05]. The proportion of eosinophils in artesunate group in BALF was significantly lower than that in asthma group [(16.63±8.58)% vs (40.44±12.94)%; t=4.336, P<0.05]. In the asthma group, the inflammatory cells infiltration of the bronchi and the perivascular area, the bronchial epithelial edema and degeneration can be observed, and the artesunate could reduce the infiltration of inflammatory cells around the bronchus and blood vessels, and the mucus secretion was also reduced in the artesunate group. Conclusion: Artesunate can improve airway hyperresponsiveness and airway inflammation in asthmatic mice and has a certain therapeutic effect on asthma.

Abstract
From November 2015 to July 2017, six patients with skin and soft tissue defects of vulva, vagina, and buttock after resection of vulvar tumors were hospitalized in our unit. All patients were female, aged 45-70 years. Among them, four patients had bilateral defects, and two patients had unilateral defect. The defect area on each side ranged from 6 cm×4 cm to 12 cm×6 cm. Internal pudendal artery perforator " angel wing" island flaps were used to repair and reconstruct the defects. The area of flaps ranged from 7 cm×5 cm to 14 cm×7 cm. The donor sites were sutured directly. All 10 flaps of 6 patients survived. Two patients had local incision infection 3 days after operation. One of the two patients was healed 2 weeks after dressing change, and the other one underwent debridement and suture 1 week after dressing change and was healed 1 week after surgery. Follow-up for 6-12 months after surgery showed no recurrence of tumors, no eversion of vagina, better shape of vulva in bilateral reconstruction cases, and slightly worse symmetry in unilateral reconstruction cases. The skin of the reconstructed area was soft, with sensations of pain, temperature, and touch recovered in varying degrees. The distance of a two-point discrimination was 20-30 mm. Linear scars were left in the flap donor sites, with no impact on squatting or striding. In vaginal examination, 1.5 to 2.0 fingers could be inserted in bilateral reconstruction cases, while 2.0 to 3.0 fingers could be inserted in unilateral reconstruction cases. The anus functioned well during defecation.

Abstract
Objective: To investigate the distribution of airway inflammation phenotypes in patients with bronchial asthma and its correlation with asthma control level. Methods: Patients who met GINA 2017 asthma diagnostic criteria from October 2017 to April 2018 in respiratory outpatient department of China-Japan Friendship Hospital were included. The clinical data of non-acute asthma patients were prospectively collected, including general data, asthma control level, pulmonary function, induced sputum cell classification, serum total IgE, exhaled nitric oxide (FeNO), blood cell classification. The correlation between phenotype distribution of airway inflammation and airway inflammation markers (eosinophils in sputum, FeNO, blood eosinophil, serum IgE) and asthma control was analyzed by correlation analysis. The correlation between sputum eosinophil level and FeNO, blood eosinophil count, serum total IgE, forced expiratory volume in one-second (FEV(1)) predicted (FEV(1)%pred) was analyzed by correlation analysis too. Results: A total of 97 asthmatic patients were enrolled. There were 38 males (39.2%) and 59 females (60.8%), aged (48±14) (range 22 to 80). Control level of asthma:13 cases (13.4%) were controlled, 39 cases(40.2%) were partially controlled and 45 cases (46.4%) were uncontrolled. The phenotypes of airway inflammation were eosinophilic 51 cases (52.6%), neutrophilic 9 cases (9.3%), mixed 35 cases (36.1%) and paucigranulocytic 2 cases (2.1%). There was no significant correlation between airway inflammation phenotype distribution, airway inflammation markers and asthma control level (P>0.05). Sputum eosinophil level was positively correlated with FeNO level in controlled and uncontrolled patients (r=0.420, P=0.008 and r=0.325, P=0.031); sputum eosinophil level was positively correlated with blood eosinophil level in uncontrolled asthma patients (r=0.328, P=0.037). There was no significant correlation between sputum eosinophil level and FEV(1)%pred (P>0.05). Conclusions: Eosinophil type is the dominant type of airway inflammation in asthmatic patients, and there is no significant correlation between airway inflammation and asthma control level. At present, airway inflammation cannot be used to assess asthma control level.

Stages of pregnancy and weaning influence the gut microbiota diversity and function in sows. J Appl Microbiol 2019; 127:867-879. [PMID: 31237071 PMCID: PMC6852164 DOI: 10.1111/jam.14344] [Citation(s) in RCA: 27] [Impact Index Per Article: 5.4] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/11/2019] [Revised: 05/07/2019] [Accepted: 05/14/2019] [Indexed: 12/17/2022]
Abstract
Aims The gut microbiota is believed to play important roles in the health of pregnant mammals, including their nutrient metabolism, immune programming and metabolic regulation. However, until recently, the shifts in gut microbiota composition and faecal and blood metabolic activity during different stages of pregnancy had not been investigated. Methods and Results We investigated the shifts in backfat thickness, plasma and faecal metabolites and gut microbiota on days 30, 60, 90 and 110 of pregnancy and on day 21 after parturition (weaning) in sows. The backfat thickness of sows did not significantly differ among the different stages of pregnancy. The plasma concentrations of lipid metabolites, including triacylglycerol (TG), total cholesterol, high‐density lipoprotein‐cholesterol, low‐density lipoprotein‐cholesterol and calcium were reduced (P < 0·05) during pregnancy. In addition, the concentration of these metabolites, except TG, reached their maximum at the time of weaning. We also found that Tenericutes, Fibrobacteres and Cyanobacteria varied significantly according to the stages of pregnancy in sows (P < 0·05). Most of the genera, such as Clostridiales, Desulfovibrio, Mogibacteriaceae and Prevotella, increased (P < 0·05) with the progression of pregnancy and decreased (P < 0·05) at weaning. The alpha diversity values (i.e., Shannon diversity and observed species) of sow gut microbiota increased (P < 0·05) from pregnancy to weaning. Pregnancy stages also significantly influenced (P < 0·05) the community structure (beta diversity) of gut microbiota. The progression of pregnancy was associated with changes in lipid metabolism and several carbohydrate‐degradation bacteria (i.e., Prevotella, Succinivibrio, Bacteroides and Parabacteroides). Conclusions Although causal links between the measured parameters remain hypothetical, these findings suggest that the increased diversity and concentration of beneficial gut microbes are associated with the metabolism of pregnant sows. Significance and Impact of the Study Manipulation of the sow gut microbiota composition may potentially influence metabolism and health during pregnancy.

Abstract
In order to explore the relationship between dietary pattern and C-reactive protein (CRP) in Xiamen residents, 2 904 subjects from 3 districts of Xiamen City were selected by a multi-stage stratified random sampling method. The food frequency questionnaire was used for dietary survey and serum CRP concentration was determined simultaneously. The dietary model was established by factor analysis and the relationship between different dietary patterns and serum CRP concentration was analyzed. Five dietary patterns were obtained by the factor analysis. After the adjustment of gender, age, occupation, education, marriage status, income, smoking, drinking and body mass index, the healthy dietary pattern was negative associated with the serum CRP concentration [OR(95%CI):0.62(0.42-0.90)]. The Serum CRP concentration of residents with a healthy dietary pattern is lower.

Abstract
Objective: To explore the predictive value of N-terminal pro-B-type natriuretic peptide (NT-proBNP) on admission on left ventricular ejection fraction (LVEF) and the in-hospital major adverse cardiac and cerebrovascular events (MACCE) in hospitalized patients with unstable angina (UA). Methods: Data of 2 972 consecutive hospitalized patients with UA in Beijing Friendship Hospital from January 2013 to September 2017 were retrospective analyzed. Patients were divided into 4 groups according to the level of NT-proBNP on admission: 733 cases with NT-proBNP lower than 61 ng/L, 749 cases with NT-proBNP between 61 and 133 ng/L, 747 cases with NT-proBNP between 133 and 326 ng/L, and 743 cases with NT-proBNP higher than 326 ng/L. LVEF and in-hospital MACCE were compared among 4 groups and the predictive value of NT-proBNP on admission on LVEF and in-hospital MACCE was determined by multiple logistical regression analysis. Results: LVEF value became lower with increasing on admission NT-proBNP value ((68.4±4.8)%, (68.2±5.2)%, (67.2±6.7)% and (62.6±10.4)%, F=77.98, P<0.01), while in-hospital MACCE was higher with increasing on admission NT-proBNP value (3.4% (25/733), 3.5% (26/749), 5.5% (41/747) and 7.3% (54/743), χ(2)=16.23, P<0.01) in NT-proBNP lower than 61 ng/L, NT-proBNP between 61 and 133 ng/L, NT-proBNP between 133 and 326 ng/L, and NT-proBNP higher than 326 ng/L group. Multiple logistic regression analysis showed that on admission NT-proBNP was an independent predictor for LVEF<50% (Exp(β)=5.875, 95%CI 3.382-10.207, P<0.001), but not predictor for in-hospital MACCE (Exp(β)=0.783, 95%CI 0.400-1.996, P=0.783). Conclusion: The on admission NT-proBNP level is an independent predictor of left ventricular systolic dysfunction (LVEF<50%), but not an independent predictor of total in-hospital MACCE in hospitalized patients with UA.

Abstract
AIM To assess the diagnostic value of the apparent diffusion coefficient (ADC) and fractional anisotropy (FA) of diffusion tensor imaging (DTI) at several anatomical locations in patients with carpal tunnel syndrome (CTS) to explore the optimal parameters and measurement location. MATERIALS AND METHODS A search was conducted using the PubMed, EBSCO, Ovid, Web of Science, and Cochrane databases to identify articles relevant to this study published before September 2017. Studies were selected and included according to strict eligibility criteria. Mean differences (MD) and 95% confidence intervals (CIs) were used to compare FA and ADC values between CTS patients and healthy subjects. Potential publication bias was investigated. RESULTS Eleven studies involving 349 CTS wrists and 278 controls were selected for the meta-analysis. A notable MD: was found for lowered FA at the level of the pisiform bone for CTS versus controls (MD: -0.11, 95% confidence interval [CI]: -1.14 to -0.07, z=5.83, p<0.001). A higher ADC was found at the pisiform bone and hamate bone levels for CTS versus controls (P: MD: 0.15, 95% CI: 0.10 to 0.20, z=5.98, p<0.001, H: MD: 0.15; 95% CI: 0.09 to 0.21, z=4.67, p<0.001). CONCLUSIONS The meta-analysis demonstrated a significant FA reduction and ADC increase in CTS patients. This result supports the use of DTI parameters in differentiating CTS patients from health subjects. The anatomical site for FA at the pisiform and ADC at the pisiform and hamate levels were more accessible than other sites for the diagnosis of CTS patients.
