Abstract
Introduction Mifepristone-misoprostol treatment for medical abortion and miscarriage are safe and effective. This study aimed to assess clinical factors associated with subsequent surgical intervention after medical termination of early viable or non-viable pregnancy. Methods This retrospective, single-center study included women who underwent medical abortion at Taipei Medical University between January 2010 and December 2019. A total of 1,561 subjects, with 1,080 viable and 481 non-viable pregnancies, who were treated with oral mifepristone 600 mg followed by misoprostol 600 mg 48 h later were included. Data of all pregnancies and medical termination of pregnancy were evaluated using regression analysis. The main outcome was successful termination of pregnancy. Results The success rate of medical abortion was comparable in women with viable and non-viable (92.13% vs. 92.93%) pregnancies. Besides retained tissue, more existing pregnancies with ultrasonographic findings were found in the non-viable pregnancy group than in the viable pregnancy group (29.4% vs. 14.1%, p = 0.011). Multivariate analysis showed that previous delivery was an independent risk factor for failed medical abortion among all included cases. In women with viable pregnancy, longer gestational age [adjusted odds ratio (aOR): 1.483, 95% confidence interval (CI): 1.224-1.797, p < 0.001] and previous Cesarean delivery (aOR: 2.177, 95% CI: 1.167-40.62, p = 0.014) were independent risk factors for failed medical abortion. Number of Cesarean deliveries (aOR: 1.448, 95% CI: 1.029-2.039, p = 0.034) was an independent risk factor for failed medication abortion in women with non-viable pregnancies. Conclusion This is the first cohort study to identify risk factors for subsequent surgical intervention in women with viable or non-viable pregnancies who had undergone early medically induced abortions. The success rate of medical abortion is comparable in women with viable and non-viable pregnancies. Previous delivery is an independent risk factor for failed medical abortion. Clinical follow-up may be necessary for women who are at risk of subsequent surgical intervention.

Abstract
Objective: To evaluate the diagnostic value of gene testing in familial hypercholesterolemia (FH) in patients with premature myocardial infarction(PMI). Methods: This study was a single center cross-sectional study. A retrospective analysis was made on PMI patients who visited the People's Hospital of Peking University from May 1, 2015 to March 31, 2017. Clinical data of patients was collected and gene testing of FH related genes low density lipoprotein receptor (LDLR), proprotein convertase subtilisin/kexin type 9 (PCSK9), apolipoprotein B(APOB) and low density lipoprotein receptor adaptor protein 1(LDLRAP1) was carried out. Clinical diagnosis of FH patients was performed using Simon Broome criteria, DLCN criteria, and FH Chinese expert consensus. Results: There were 188 males (83.6%) among 225 PMI patients, and the age of the first myocardial infarction was (46.6±7.2) years old. Ten patients carried FH pathogenic or possibly pathogenic mutations (4.4%). Compared with Simon Broome standard, DLCN standard and FH Chinese expert consensus, gene testing increased the diagnostic rate of FH by 53.3%, 33.3% and 42.1% respectively. Conclusion: Gene testing is helpful to improve the diagnosis of FH, and it is important to start the standard treatment of FH as early as possible in patients with premature myocardial infarction.

Abstract
Objective: To investigate respiratory virus infection in children with septic shock in pediatric care units (PICU) in China and its influence on clinical outcomes. Methods: The clinical data of children with septic shock in children's PICU from January 2018 to December 2019 in 10 Chinese hospitals were retrospectively collected. They were divided into the pre-COVID-19 and post-COVID-19 groups according to the onset of disease, and the characteristics and composition of respiratory virus in the 2 groups were compared. Matching age, malignant underlying diseases, bacteria, fungi and other viruses, a new database was generated using 1∶1 propensity score matching method. The children were divided into the respiratory virus group and non-respiratory virus group according to the presence or absence of respiratory virus infection; their clinical characteristics, diagnosis, and treatment were compared by t-test, rank sum test and Chi-square test. The correlation between respiratory virus infection and the clinical outcomes was analyzed by logistic regression. Results: A total of 1 247 children with septic shock were included in the study, of them 748 were male; the age was 37 (11, 105) months. In the pre-and post-COVID-19 groups, there were 530 and 717 cases of septic shock, respectively; the positive rate of respiratory virus was 14.9% (79 cases) and 9.8% (70 cases); the seasonal distribution of septic shock was 28.9% (153/530) and 25.9% (185/717) in autumn, and 30.3% (161/530) and 28.3% (203/717) in winter, respectively, and the corresponding positive rates of respiratory viruses were 19.6% (30/153) and 15.7% (29/185) in autumn, and 21.1% (34/161) and 15.3% (31/203) in winter, respectively. The positive rates of influenza virus and adenovirus in the post-COVID-19 group were lower than those in the pre-COVID-19 group (2.1% (15/717) vs. 7.5% (40/530), and 0.7% (5/717) vs. 3.2% (17/530), χ2=21.51 and 11.08, respectively; all P<0.05). Rhinovirus virus were higher than those in the pre-Covid-19 group (1.7% (12/717) vs. 0.2% (1/530), χ2=6.51, P=0.011). After propensity score matching, there were 147 cases in both the respiratory virus group and the non-respiratory virus group. Rate of respiratory failure, acute respiratory distress, rate of disseminated coagulation dysfunction, and immunoglobulin usage of the respiratory virus group were higher than those of non-respiratory virus group (77.6% (114/147) vs. 59.2% (87/147), 17.7% (26/147) vs. 4.1% (6/147), 15.6% (25/147) vs. 4.1% (7/147), and 35.4% (52/147) vs. 21.4% (32/147); χ2=11.07, 14.02, 11.06 and 6.67, all P<0.05); and PICU hospitalization of the former was longer than that of the later (7 (3, 16) vs. 3 (1, 7)d, Z=5.01, P<0.001). Univariate logistic regression analysis showed that the presence of respiratory viral infection was associated with respiratory failure, disseminated coagulation dysfunction, the use of mechanical ventilation, and the use of immunoglobulin and anti-respiratory viral drugs (OR=2.42, 0.22, 0.25, 0.56 and 1.12, all P<0.05). Conclusions: The composition of respiratory virus infection in children with septic shock is different between pre and post-COVID-19. Respiratory viral infection is associated with organ dysfunction in children with septic shock. Decreasing respiratory viral infection through respiratory protection may improve the clinical outcome of these children.

Abstract
BACKGROUND In 2018, 84 615 patients in Taiwan received hemodialysis, of which about 62% to 97% suffered from fatigue. Fatigue caused by hemodialysis may be mental or physical. However, the detailed mechanism remains unclear. This study aimed to evaluate whether far-infrared stimulation of the Neiguan acupoint (P6) could effectively reduce fatigue and improve heart rate variability (HRV) in hemodialysis patients. METHODS We conducted a two-arm, randomized trial in a hemodialysis center between March 2015 and March 2016. A total of 73 hemodialysis patients were included and were randomly assigned to an experimental group (n = 37) and a control group (n = 36). The experimental group received far-infrared radiation on Neiguan acupoint during hemodialysis for 12 weeks. The outcomes were fatigue level and HRV. RESULTS All patients showed moderate fatigue ( M = 26.00 ± 13.01, range = 0-78) at baseline. Far-infrared stimulation on Neiguan acupoint significantly reduced overall fatigue ( β = 24, p < 0.001) and improved HRV ( β = 74.36, p < 0.001). Compared to the control group, the experiment group had significantly reduced fatigue levels in all aspects such as reduced energy and motivation ( β = -2.97, p < 0.001), reduced physical strength ( β = -1.28, p < 0.01), reduced mental capability ( β = -2.38, p < 0.001), reduction in daily activities ( β = -1.48, p < 0.01), depressed mood and loss of control ( β = -1.21, p < 0.05) as well as increased autonomous nervous system activity ( β = 14.71, p < 0.01) in the third month of stimulation. CONCLUSION Far-infrared stimulation of the Neiguan acupoints effectively reduces fatigue and increases autonomic nervous system activity in hemodialysis patients.

Moxibustion for Managing Postoperative Urinary Retention After Hemorrhoidectomy and Anorectal Surgeries: A Systematic Review and Meta-Analysis of Randomized Controlled Trials. J Perianesth Nurs 2023; 38:881-891. [PMID: 37589632 DOI: 10.1016/j.jopan.2023.01.020] [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: 06/13/2022] [Revised: 12/05/2022] [Accepted: 01/21/2023] [Indexed: 08/18/2023]
Abstract
PURPOSE Common surgical procedures for conditions affecting the anus and rectum such as hemorrhoidectomy are associated with high risks of postoperative urinary retention (POUR). Little is known about the efficacy of moxibustion in managing POUR after such surgical procedures. This systematic review and meta-analysis aimed to review the related literature and synthesize data on the effectiveness of moxibustion in managing POUR after common anorectal surgeries. DESIGN A systematic review and meta-analysis of randomized controlled trials (RCTs). METHODS PubMed, EMBASE, CENTRAL, Chinese National Knowledge Infrastructure (CNKI), VIP information, and Wanfang databases were searched to October 1, 2021 using the keywords urinary retention, moxibustion, and moxa. Randomized controlled trials (RCTs) investigating patients who had developed POUR after hemorrhoidectomy or other anorectal surgeries were eligible for inclusion. Patients receiving moxibustion formed the intervention group and the control group received usual care alone. Primary outcomes were markedly effective rate, defined as spontaneous voiding with complete symptom relief within 30 to 60 minutes after treatment; and total effective rate (ie, markedly effective rate plus effective rate, defined as spontaneous voiding with partial relief of symptoms within 60 minutes to 4 hours after treatment). Secondary outcome was time to first urination after treatment. FINDINGS Thirty-four RCTs met the eligibility criteria. Pooled analysis revealed that the markedly effective rate was significantly higher in the moxibustion group than that in the control group (pooled RR = 2.53, 95% CI = 2.17-2.95), and the total effective rate in the moxibustion group was also higher than that in the control group (pooled RR = 5.02, 95% CI = 4.01-6.28). The intervention group had significantly shorter times to first urination than controls (pooled effect = -2.81, 95% CI = -2.06 to -3.56). CONCLUSIONS Moxibustion appears superior to usual care in relieving POUR after common anorectal surgeries. Future studies are still warranted to confirm these findings.

Abstract
Objective: To investigate the relationship between nutritional status, body composition and symptoms of Parkinson's disease (PD). Methods: The study was conducted among 102 PD patients between November 2020 to April 2021 in the outpatient and inpatient of Neurology department of the Second Affiliated Hospital of Suzhou University. Basic data, such as age, gender, course of disease and Hoehn-Yahr (H-Y) stage of the patients, were collected. In the "open" state, the Unified Parkinson's Disease Rating Scale (UPDRS) and other scales were used to evaluate the clinical symptoms of PD patients. The nutritional status of PD patients was evaluated by the micro-nutrition rating Scale (MNA), and the body composition data of PD patients was measured by the body composition analyzer.The patients were divided into three groups according to the MNA: well-nourished group(45 cases), malnutrition-risk group (43 cases)and malnutrition group(14 cases). Body composition, laboratory tests, bone density, and symptoms of PD were compared among the three groups. Results: Among 102 PD patients, 48 were males (47.1%) and 54 were females (52.9%), aged 42-86 (66±9) years old. Compared with the malnutrition-risk group, lymphocytes in the malnutrition group [(1.45±0.48) × 109/L vs (1.76±0.43)×109/L], uric acid [(227±54) μmol/L vs (282±63) μmol/L] were all low, and the difference was statistically significant (all P<0.05). Compared with the well-nourished group, hemoglobin [(125±17) g/L vs (136±14) g/L], prealbumin [(0.23±0.05) g/L vs (0.27±0.06) g/L], and uric acid [(227±54) μmol/L vs (312±76) μmol/L] and Retinol binding protein [(33±7) mg/L were lower than (39±10) mg/L] in the malnutrition group, the difference was statistically significant (P<0.05). Except for the visceral fat area and body fat percentages, there was no significant difference in body composition indexes and bone mineral density T-value between the malnutrition-risk and malnutrition groups (P<0.05). Compared with the well-nourished group, the body fat [(16±6) kg vs (20±6) kg], the percentage of body fat [(26±9)% vs (29±7)%], the waist-hip ratio [(0.86±0.05) vs (0.89±0.05)], and the upper arm circumference [(29.00±2.59) cm vs (30.74±2.75) cm] in the malnutrition risk group were lower, and the difference was statistically significant (P<0.05). There were statistically significant differences in all body composition indicators and T-values of bone density between the malnourished and well nourished groups (all P<0.05). The MNA score of PD patients was negatively correlated with UPDRS Ⅰ, UPDRS Ⅱ, and UPDRS Ⅳ scores (r=-0.347, -0.364, -0.303, all P<0.05); Body composition indicators: total body water and inorganic salts were negatively correlated with UPDRS-I (r=-0.206, -0.223, all P<0.05), and body fat was negatively correlated with levodopa Equivalent dose (LED) (r=-0.209, P<0.05) Conclusions: The malnutrition risk and incidence of malnutrition in PD patients are high; lymphocyte, uric acid, hemoglobin, Retinol binding protein, body composition and bone mineral density were low in malnutrition group. MNA score of PD patients was negatively correlated with Parkinson's disease symptoms.

Predictive Role of Neutrophil-Percentage-to-Albumin Ratio (NPAR) in Nonalcoholic Fatty Liver Disease and Advanced Liver Fibrosis in Nondiabetic US Adults: Evidence from NHANES 2017-2018. Nutrients 2023; 15:nu15081892. [PMID: 37111111 PMCID: PMC10141547 DOI: 10.3390/nu15081892] [Citation(s) in RCA: 4] [Impact Index Per Article: 4.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/10/2023] [Revised: 03/31/2023] [Accepted: 04/11/2023] [Indexed: 04/29/2023] Open
Abstract
Nonalcoholic fatty liver disease (NAFLD) is highly prevalent globally and includes chronic liver diseases ranging from simple steatosis to nonalcoholic steatohepatitis (NASH). The neutrophil-to-albumin ratio (NPAR) is a cost-effective, readily available biomarker of inflammation used to assess cancer and cardiovascular disease prognosis, and it may be of predictive value in NAFLD. This study was to evaluate the associations between the NPAR, the neutrophil-to-lymphocyte ratio (NLR), and the presence of NAFLD or advanced liver fibrosis, and to assess the predictive value of the NPAR in NAFLD in a nationally representative database. This population-based, cross-sectional, retrospective study analyzed the secondary data of adults with NAFLD or advanced liver fibrosis extracted from the National Health and Nutrition Examination Survey (NHANES) database 2017-2018. NHANES participants with complete information of vibration-controlled transient elastography (VCTE) and controlled attenuation parameter (CAP) were enrolled. A logistic regression analysis was used to determine the associations between the variables in the participants with and without NAFLD or advanced liver fibrosis. The mean values of the lymphocyte counts, neutrophil counts, NPAR, aspartate aminotransaminase (AST), alanine aminotransaminase (ALT), total cholesterol, triglycerides, and HbA1c were significantly higher in the participants with NAFLD than in those without NAFLD or advanced liver fibrosis. The mean blood albumin levels of the subjects without NAFLD or advancing fibrosis were considerably greater than those of the individuals with these conditions. The mean values of the NLR, NPAR, AST, ALT, triglycerides, lymphocyte count, neutrophil count, and HbA1c were significantly higher in patients with advanced fibrosis than in those without advanced fibrosis. A multivariate analysis showed that per unit increases in both the NLR and NPAR were significantly associated with an increased risk of developing NAFLD, while neither the NLR nor NPAR was significantly associated with higher odds of advanced fibrosis. In conclusion, the novel biomarker NPAR demonstrates a good association with NAFLD, along with participants' clinical characteristics, in a nationwide population. The NPAR may serve as a biomarker for NAFLD and help clinicians refine the diagnosis and treatment of chronic liver disease.

Abstract
Objective: To identify the risk factors in mortality of pediatric acute respiratory distress syndrome (PARDS) in pediatric intensive care unit (PICU). Methods: Second analysis of the data collected in the "efficacy of pulmonary surfactant (PS) in the treatment of children with moderate to severe PARDS" program. Retrospective case summary of the risk factors of mortality of children with moderate to severe PARDS who admitted in 14 participating tertiary PICU between December 2016 to December 2021. Differences in general condition, underlying diseases, oxygenation index, and mechanical ventilation were compared after the group was divided by survival at PICU discharge. When comparing between groups, the Mann-Whitney U test was used for measurement data, and the chi-square test was used for counting data. Receiver Operating Characteristic (ROC) curves were used to assess the accuracy of oxygen index (OI) in predicting mortality. Multivariate Logistic regression analysis was used to identify the risk factors for mortality. Results: Among 101 children with moderate to severe PARDS, 63 (62.4%) were males, 38 (37.6%) were females, aged (12±8) months. There were 23 cases in the non-survival group and 78 cases in the survival group. The combined rates of underlying diseases (52.2% (12/23) vs. 29.5% (23/78), χ2=4.04, P=0.045) and immune deficiency (30.4% (7/23) vs. 11.5% (9/78), χ2=4.76, P=0.029) in non-survival patients were significantly higher than those in survival patients, while the use of pulmonary surfactant (PS) was significantly lower (8.7% (2/23) vs. 41.0% (32/78), χ2=8.31, P=0.004). No significant differences existed in age, sex, pediatric critical illness score, etiology of PARDS, mechanical ventilation mode and fluid balance within 72 h (all P>0.05). OI on the first day (11.9(8.3, 17.1) vs.15.5(11.7, 23.0)), the second day (10.1(7.6, 16.6) vs.14.8(9.3, 26.2)) and the third day (9.2(6.6, 16.6) vs. 16.7(11.2, 31.4)) after PARDS identified were all higher in non-survival group compared to survival group (Z=-2.70, -2.52, -3.79 respectively, all P<0.05), and the improvement of OI in non-survival group was worse (0.03(-0.32, 0.31) vs. 0.32(-0.02, 0.56), Z=-2.49, P=0.013). ROC curve analysis showed that the OI on the thind day was more appropriate in predicting in-hospital mortality (area under the curve= 0.76, standard error 0.05,95%CI 0.65-0.87,P<0.001). When OI was set at 11.1, the sensitivity was 78.3% (95%CI 58.1%-90.3%), and the specificity was 60.3% (95%CI 49.2%-70.4%). Multivariate Logistic regression analysis showed that after adjusting for age, sex, pediatric critical illness score and fluid load within 72 h, no use of PS (OR=11.26, 95%CI 2.19-57.95, P=0.004), OI value on the third day (OR=7.93, 95%CI 1.51-41.69, P=0.014), and companied with immunodeficiency (OR=4.72, 95%CI 1.17-19.02, P=0.029) were independent risk factors for mortality in children with PARDS. Conclusions: The mortality of patients with moderate to severe PARDS is high, and immunodeficiency, no use of PS and OI on the third day after PARDS identified are the independent risk factors related to mortality. The OI on the third day after PARDS identified could be used to predict mortality.

Abstract
Introduction Sleep disorders are commonly encountered in modern populations. This cross-sectional study aimed to investigate the associations between triglyceride glucose (TyG) index and poor sleep patterns in non-diabetic adults. Methods Data of non-diabetic adults aged 20-70 years were extracted from the US National Health and Nutrition Examination Survey database 2005-2016. Pregnant women, individuals with diabetes and cancer history, and individuals lacking complete data on sleep patterns or parameters for calculating TyG index were excluded. Poor sleep pattern was defined as having two or more following conditions: (1) abnormal sleep duration, defined as less than 7 h or longer than 9 h; (2) self-reported trouble sleeping; and (3) physician-confirmed sleep disorders. Associations between poor sleep patterns, TyG index, and an additional index incorporating body mass index (BMI), TyGBMI, and other study variables were determined by univariable and multivariable logistic regression analysis. Results Among 9,390 included participants, 1,422 had poor sleep patterns and 7,968 did not. The individuals with poor sleep patterns had a higher mean TyG index, were older, had higher BMI, and had higher proportions of hypertension and history of CVD than those without poor sleep pattern (all p < 0.001). Multivariable analysis showed no significant association between poor sleep pattern and TyG index. However, among the components of poor sleep pattern, TyG index in the highest quartile (Q4) was significantly associated with trouble sleeping [adjusted OR (aOR): 1.46, 95%CI: 1.04-2.03) as compared with the lowest TyG quartile (Q1). In addition, TyG-BMI in Q4 was indepently associated with increased likelihood for poor sleep patterns (aOR: 2.18, 95%CI: 1.61-2.95), trouble sleeping (aOR: 1.76, 95%CI: 1.30-2.39), abnormal sleep duration (aOR: 1.41, 95%CI: 1.12-1.78), and sleep disorders (aOR: 3.11, 95%CI: 2.08-4.64) as compared to Q1. Discussion Among US adults without diabetes, elevated TyG index is correlated with self-reported trouble sleeping, independent of BMI. Future studies should build upon this preliminary work and examine these associations longitudinally and through treatment trials.

Methods: General information, sarcopenia-related indicators, neuropsychological tests and MTA score were collected in 80 confirmed AD patients (41 mild and 39 moderate patients) and 43 normal controls (NC) from the Memory Disorders Clinic of Department Of Neurology in the Second Affiliated Hospital of Soochow University between January and December 2021. Appendicular skeletal muscle mass index (ASMI), grip strength and 5-times sit-to-stand time and 6-m gait speed were used for assessing muscle mass, muscle strength and physical function, respectively. Cognitive function was assessed by Mini-Mental State Examination (MMSE), Montreal Cognitive Assessment scale (MoCA), Memory and Executive Screening Scale (MES), Digit Symbol Substitution Test (DSST), Digital Span Test (DST) and Verbal Fluency Task (VFT), respectively. DST included Forward Digit Span Test (FDST) and Backward Digit Span Test (BDST). All the subjects underwent 3.0T coronal three-dimensional gradient echo sequence MRI. MTA scale was performed to evaluate the degree of medial temporal lobe atrophy. The differences in the sarcopenia-related indicators, cognitive score and MTA score were analyzed among the three groups, and the partial correlation analysis was performed between the inter-groups. Results: Eighty AD patients (24 males and 56 females) were included, aged (72±7) years old, with 41 mild and 39 moderate patients. Meanwhile, 43 NC included 19 males and 24 females, with a mean age of (70±6) years old. The disease duration in moderate AD patients was longer than that of mild AD patients [34.0 (25.0, 43.5) months vs 24.0 (11.0, 34.0) months, P<0.001]. The differences of sarcopenia-related indicators and MTA score among the three groups were statistically significant (all P<0.001), including 5-times sit-to-stand time [(13.6±1.8) s vs (11.5±1.7) s vs (10.3±1.9) s, P<0.001] and MTA score [2.0 (2.0, 3.0) vs 1.0 (1.0, 2.0) vs 0 (0, 0), P<0.001]. In neuropsychological tests, compared to the NC group, MMSE, MoCA, MES and VFT scores in mild and moderate AD groups were lower (all P<0.001); meanwhile, compared to the mild AD group, the moderate group had lower MMSE, MoCA, MES, DSST and VFT scores (all P<0.001). In sarcopenia-related indicators, muscle strength in particular was correlated with widespread cognitive functioning domains and MTA score in AD patients. Grip strength was positively correlated with MMSE, MoCA , MES, FDST (r=0.387, 0.418, 0.522 and 0.484, respectively, all P<0.001), DSST (r=0.327, P=0.006) and VFT score (r=0.354, P=0.003), and negatively correlated with MTA score (r=-0.631, P<0.001). 5-times sit-to-stand time was negatively correlated with MMSE, MoCA, MES, DSST, FDST, VFT score (r=-0.583, -0.587, -0.814, -0.591, -0.552 and -0.485, respectively, all P<0.001), and BDST (r=-0.355, P=0.003) strongly positively correlated with MTA score (r=0.836, P<0.001). ASMI was positively correlated with MMSE, MoCA, MES, DSST, FDST score (r=0.257, 0.238, 0.428, 0.282 and 0.364, respectively, all P<0.05), and negatively correlated with MTA score (r=-0.377, P=0.001). 6-m gait speed was positively correlated with MMSE, MoCA, MES, DSST, FDST score (r=0.419, 0.486, 0.699, 0.559 and 0.500, respectively, all P<0.001), BDST and VFT score (r=0.384、0.377, respectively, both P=0.001), and strongly negatively correlated with MTA score (r=-0.803, P<0.001). Conclusions: Patients with mild to moderate AD have widespread cognitive impairment. Muscle mass, muscle strength and physical function are all significantly impaired. Compared to muscle mass and physical function, decreased muscle strength is significantly associated with widespread cognitive decline and increased degree of medial temporal lobe atrophy.

Abstract
Objective: To explore the diagnostic value of third ventricle width (TVW) measured by transcranial ultrasound (TCS) in the clinical diagnosis of Alzheimer's disease (AD) by analyzing and comparing the image characteristics of TVW in AD patients and healthy controls, and its correlation with cranial magnetic resonance medial temporal lobe atrophy (MTA) visual score and neuropsychological characteristics. Methods: TCS examination, MTA score and neuropsychological tests were performed in 39 confirmed AD and 41 normal controls from the Second Affiliated Hospital of Soochow University between January and July 2021. The correlation of TVW with MTA score and neuropsychological characteristics was analyzed and compared between the two groups. Results: A total of thirty-nine AD patients were enrolled, with 28 males and 11 females, aged (73±9) years, including 18 mild, 20 moderate, and 1 severe AD patient. Meanwhile, 41 healthy controls were also included, with 24 males and 17 females, aged (69±6) years old. TVW in AD patients was significantly wider than that in normal controls [0.76(0.66, 0.87) cm vs 0.50(0.44, 0.56) cm, P<0.001]. In neuropsychological tests, compared with normal controls, AD patients showed impaired performances in several cognitive functions, and there were statistically significant differences in delayed memory [0(0, 0) vs 4.0(4.0, 5.0), P<0.001], naming [2.0(1.0, 3.0) vs 3.0(2.0, 3.0), P<0.001], executive function [2.0(2.0, 3.0) vs 3.0(2.5, 3.0), P<0.001], language [0.0(0.0, 2.0) vs 3.0(2.0, 3.0), P<0.001] and other aspects between AD patients and normal controls (all P<0.05). TVW was negatively correlated with immediate memory (r=-0.339, P=0.035), delayed recall (r=-0.523, P<0.001), attention and computing power (r=-0.409, P=0.045), visual space and executive function (r=-0.333, P=0.039), but positively correlated with the atrophy of the medial temporal lobe (r= 0.552, P<0.001). Conclusions: TCS can be used to measure TVW in AD patients. When combined with MTA score and neuropsychological tests, it can provide a reliable objective basis for the clinical diagnosis of AD.

Abstract
Objective: To analyze the eligibility of empirical antibiotic therapy in culture positive sepsis in the pediatric intensive care unit (PICU), and to explore the application of antibiotic de-escalation (ADE) in children with sepsis and its impact on prognosis. Methods: A total of 123 children with sepsis-associated organ dysfunction or septic shock admitted to the PICU of Shengjing Hospital of China Medical University from January 2018 to December 2020 were retrospectively analyzed. The general information, laboratory tests, the use of empirical anti-bacterial drugs and the application of ADE were collected. According to the adjustment of anti-bacterial drugs, these children were divided into ADE group and non-ADE group. Comparisons between groups were performed with unpaired Student t test, or Mann-Whitney U test, or chi-square test or Fisher exact test. Results: In these 123 children, 70 were males and 53 were females, the age was 11.4 (2.8, 56.5) months. Body fluid culture was detected positive in 41 children including 3 children (7.3%) who received inadequate empirical antibiotic therapy and 38 children (92.7%) who received adequate empirical antibiotic therapy. Excluding 10 children who received appropriate therapy, 28 received unnecessary broad-spectrum antibiotics. There were no significant differences regarding the PICU all-cause mortality rates, length of PICU stay, hospitalization cost, duration of mechanical ventilation, as well as incidences of re-infection between the ADE group (n=46) and non-ADE group (n=77) (all P>0.05). However, among the 101 children who have used antibiotics against multidrug-resistant organism, the duration of such antibiotics use in ADE group (n=43) was shorter than that in non-ADE group (n=58) (5.0 (4.0, 12.0) vs. 9.5 (7.0, 13.0) d, Z=-3.14, P=0.002). Conclusions: Overuse of unnecessary broad-spectrum empirical antibiotics is very common, but the application of ADE is rather disappointing. ADE can reduce the use of anti-bacterial drugs against multi-drug resistant bacteria without significant adverse effects on prognosis in children with sepsis.

Abstract
Objective: To study the relationship between emotional apathy and motor symptoms, sleep, and cognitive function in patients with early Parkinson's disease (PD). Methods: One hundred and twenty-nine early PD patients who were treated in the Second Affiliated Hospital of Soochow University from June to October 2020 were included, including 82 male and 47 female patients. The emotional apathy was assessed by modified apathy rating scale (MAES). The above 129 patients were divided into 67 patients in the PD with emotional apathy group (MAES>14 points) and 62 patients in the PD without emotional apathy group (MAES≤ 14 points). Age, gender, course of disease and levodopa equivalent dose were also collected. Hoehn-Yahr stage and unified Parkinson's disease rating scale PartⅢ(UPDRS-Ⅲ), Pittsburgh Sleep Quality Index (PSQI), polysomnography, and Montreal Cognitive Assessment Scale (MoCA) were used to evaluate the motor symptoms, sleep and cognitive functions of patients with early PD, and the clinical characteristics of patients with early PD with apathywere determined. Results: Compared with PD patients without apathy, those with apathy had longer disease duration [M(Q1,Q3)][5.0 (3.0, 7.0) years vs 3.0 (2.0, 5.0) years, P=0.006] and severer motor symptoms [20.0 (10.0, 28.0) vs 14.0 (8.5, 23.0), P=0.047]. There was no significant difference in PSQI score between the two groups. Among the 33 patients who completed polysomnography, compared with PD patients without apathy (n=16), those with apathy (n=17) had a longer rapid eye movement (REM) sleep latency [150 (124, 184) min vs 87 (57, 133) min, P=0.035)] and more frequent periodic limb movements in the REM phase(P=0.042).The REM sleep ratio (r=0.373, P=0.042), apnea-hypopena index (AHI)(r=0.374, P=0.046) and oxygen deficit index (r=0.409, P=0.025) were positively correlated with the degree of apathy in PD patients. PD patients with apathy had relatively poorer performance in cognition assessment than those without apathy and total MoCA score was inversely correlated with the degree of apathy (r=-0.231, P=0.017). Conclusion: Early PD patients with apathy have objective sleep disorders dominated by REM sleep disorders, which can have a negative impact on cognitive function.

Abstract
Objective: To investigate the risk factors for death in children with acute necrotizing encephalopathy (ANE) in pediatric intensive care unit (PICU). Methods: This was a multicenter retrospective study. Thirty-nine children with ANE were from PICUs in 4 centers from December 1, 2014 to December 1, 2020. The 4 participating centers were Beijing Children's Hospital, Shengjing Hospital of China Medical University, Hebei Children's Hospital, and Bao'an Maternity & Child Health Hospital. Patients were divided into survival and non-survival groups by the outcome at discharge, and the differences in clinical data between the two groups were compared. Risk factors for death in children with ANE and the odds ratios (OR) were analyzed by univariable Logistic regression. Results: Thirty-nine children with ANE were included. There were 18 males and 21 females. The median onset age was 30 months. The mortality at discharge was 41% (16/39). The onset age of most patients (74%, 29/39) was younger than 4 years old. Influenza virus was the most common precursor infection (80%, 20/25). Patients with shock at PICU admission were more common in the non-survival group (12/16 vs. 17% (4/23), P=0.001). Glasgow coma score (GCS) at PICU admission was significantly lower in the non-survival group than survival group (3 (3, 6) vs. 6 (5, 7), Z=-2.598, P=0.009). The optimal cut-off value was 4. The proportion of patients with GCS ≤ 4 at PICU admission was higher in the non-survival group (10/16 vs. 22% (5/23), P=0.018). ANE severity score (ANE-SS) at PICU admission was significantly higher in the non-survival group (5 (2, 6) vs. 2 (1, 4), Z=-2.436, P=0.015). The proportion of patients with high risk ANE-SS was higher in non-survival group than the survival group (9/16 vs. 22% (5/23), P=0.043). The proportion of application of high-dose methylprednisolone (20 mg/(kg·d)) was significantly higher in survival group than non-survival group (43% (10/23) vs. 1/13, P=0.031). Univariable Logistic regression indicated that risk factors for death in children with ANE were shock (OR=14.250, 95%CI 2.985-68.018, P=0.001), GCS≤4 (OR=6.000, 95%CI 1.456-24.733, P=0.013) and high risk ANE-SS (OR=4.629, 95%CI 1.142-18.752, P=0.032) at PICU admission. Conclusions: ANE usually occurs in children under 4 years old after influenza infection. Shock, GCS≤4 and high risk ANE-SS at PICU admission were risk factors for death in children with ANE. High-dose methylprednisolone may improve the prognosis of children with ANE.

Abstract
Objective: To evaluate the transcranial sonographic characteristics in patients with Parkinson's disease (PD) with symptoms of restless legs syndrome (RLS). Methods: Patients with diagnosis of definite PD from the Second Affiliated Hospital of Soochow University and 3 other participating hospitals between September 2018 and December 2019 were consecutively enrolled. Concurrent RLS symptoms were determined using Non-motor Symptoms Questionnaire. Transcranial sonography (TCS) and clinical assessments were performed during the same time and the related variables were compared between the two groups using t-test, non-parametric test, Chi-square test and Spearman correlation analysis, respectively. Results: Among 349 patients with PD, the prevalence of RLS symptoms was 22.6%. Compared to patients without RLS symptoms, those with RLS had longer disease duration (43.0 (24.0, 91.0) months vs 37.0 (20.0, 60.0) months, P<0.05) and higher Hoehn-Yahr stage (2.5 (2.0, 3.0) vs 2.0 (1.5, 2.5), P<0.01).TCS revealed that patients with RLS symptoms were more likely to have abnormality in the raphe nucleus (21.50% vs 7.78%, χ²=15.9, P<0.001) and increased third ventricle width ((6.22±1.97) mm vs (5.16±1.90) mm, P<0.001). No significant differences were found regarding parameters of substantia nigra. Conclusions: Concurrent RLS symptoms are common in PD patients. Abnormal echogenicity of raphe nucleus and increased third ventricle width could be characteristics of TCS in PD patients with RLS symptoms.

Abstract
Objectve: To evaluate the relationship of Parkinson's disease(PD) patients' sleep quality and depression with burden, quality of life, and depression of their caregivers. Methods: A total of 120 PD patients (68 males and 52 females) and their caregivers (48 males and 72 females) from Changshu Hospital Affiliated to Nanjing University of Chinese Medicine between January 2017 and June 2019 were recruited. Patients' sleep quality, depression and quality of life was evaluated. Burden, quality of life, quality of sleep, and depression of caregivers were assessed by the Caregivers Burden Questionnaire (CBI), Health Survey Brief (SF-36), Pittsburgh Sleep Quality Index (PQS1) and Hamilton Depression Scale (HAMD), meanwhile, the correlation between relevant factors was analyzed. Results: The CBI of caregivers was positively correlated with the unified Parkinson's disease rating scale (UPDRS)-Ⅲ scores of PD patients (r=0.436, P<0.05). The CBI, SF-36GH, SF-36MH, HAMD and PSQI scores of caregivers were positively correlated with Parkinson's disease sleep scale (PDSS) scores of PD patients (r=0.546, 0.762, 0.528, 0.562 and 0.522, respectively, all P<0.01). The caregiver's CBI score was positively correlated with PD patients' Epworth sleepiness score (ESS) score (r=0.442, P<0.05), and caregiver's CBI, SF-36GH, SF-36MH, HAMD, PSQI scores were positively correlated with PD patients' HAMD scores (r=0.765, 0.813, 0.635, 0.884 and 0.601, respectively, all P<0.01). The caregiver's CBI score was positively correlated with the PDQ-39 score of PD patients (r=0.834, 0.452, 0.463, 0.421 and 0.387, respectively, all P<0.05). Multiple regression analysis indicated that the caregiver's CBI score was significantly correlated with the patient's PDQ-39, PDSS and HAMD scores (r=0.512, 0.645 and 0.635, respectively, all P<0.01), and the caregiver's SF-36GH score was significantly correlated with the patient's PDQ-39, PDSS and HAMD scores (r=0.452, 0.682 and 0.506, respectively, all P<0.01). The caregiver's SF-36MH score was significantly correlated with the patient's PDQ-39, PDSS and HAMD scores (r=0.426, 0.608 and 0.598, respectively, all P<0.01). There was significant correlations between the caregiver's HAMD score and the patient's PDSS and HAMD scores (r=0.568 and 0.496, both P<0.01), and the PSQI score of the caregiver was significantly correlated with the PDSS and HAMD scores of the patient (r=0.532 and 0.461, both P<0.01). Conclusions: This current study underscores the presence of a significant relationship of patient's sleep quality with caregiver's burden, quality of life, depression and sleep quality. Specifically, sleep quality and depression of the patients are independent predictors for burden, quality of life and sleep quality of the caregivers.

Abstract
Objective: To investigate the clinicopathological features, diagnosis and prognosis of polymorphous low-grade neuroepithelial tumor of the young (PLNTY). Methods: Two cases of PLNTY diagnosed during January 2016 to December 2019 were collected from Ningbo Diagnostic Pathology Center, Zhejiang, China. The clinical features, histopathological characteristics, immunohistochemical and molecular genetic findings were analyzed and the relevant literature was reviewed. Results: The two patients were both female, at the ages of 14 and 25 years, respectively. Both patients presented with seizure attacks. The imaging study showed a mixed signal in the cerebral cortex, located in the occipital and temporal lobes, respectively. Microscopically, the tumors were characterized by the invariable presence of oligodendroglioma-like appearance, often with calcification. Immunohistochemically, the tumors were diffusely and intensely CD34 positive with ramified, CD34-expressing neural elements in regional cortex. The tumors were positive for GFAP, Olig2 and ATRX, and negative for IDH1, Neu N, nestin and EMA. The Ki-67 labeling index was less than 2%. The case number 2 harbored the BRAF V600E mutation, while the case number 1 was negative for both the BRAF V600E mutation and 1p/19q codeletion. Both patients recovered very well and were free of seizures after the following-up of 2 and 24 months, respectively. Conclusions: PLNTY is an uncommon neuroepithelial tumor. Histopathologic and immunohistochemical examinations are necessary for establishing the diagnosis and for excluding oligodendroglioma. PLNTY should be considered as a benign tumor corresponding to WHO Grade I. The prognosis is overall good after complete tumor-resection.

Abstract
Objective: To analyze the clinic features of isolated myeloid sarcoma (IMS) involving the pleural cavity. Methods: A case of pleural isolated myeloid sarcoma (PIMS) with pleural effusion as the first manifestation was described. The related cases in literatures were reviewed with"myeloid sarcoma"and"pleural effusions"as the keywords to search China HowNet, Wanfang database and PubMed database. Results: A 59-year-old man complained of right chest pain for 2 months and worsening pain with distress and shortness of breath for 2 weeks. The chest CT scan showed pleural effusion on the right side. Flow cytometric analysis of pleural fluid showed that a population of blasts with CD34 expressing was 37.6% of the total nucleated cells. The pleural biopsy through medical thoracoscopy indicated lymphoproliferative lesions by pathological examination. Immunohistochemistry was performed on pleural histological sections and cell blocks of pleural effusions, which showed CD34 and CD117 positive expression. The diagnosis of PIMS was finally made. Two literature papers with 2 complete cases were found and reviewed. The 3 cases were analyzed. There were 2 males and 1 female. The age was 59, 51, 56 years respectively. One case was a patient with 3 weeks of right upper quadrant and epigastric pain, nausea, and weight loss. Cytological examination of the pleural fluid showed numerous poorly differentiated malignant cells. Histology from an open laparotomy in duodenal biopsies, gallbladder, and mesenteric lymph nodes supported the diagnosis of IMS. The other case was a patient with 6 weeks of dyspnea and a large swelling in the upper vestibular region. Thoracentesis showed 82% myeloid blasts in the pleural fluid. A gingival biopsy showed a diffuse infiltration by cells with a blastic appearance and supported IMS. Conclusion: PIMS was a very rare cause of pleural effusions. The cytological and histopathological evidences were useful to diagnose IMS involving the pleural cavity.

Abstract
Objective: To investigate the epidemiological characteristics and transmission chain of COVID-19 in two families, and to provide scientific evidence for effective prevention and control measures. Methods: Field epidemiological investigation was conducted for the COVID-19 cases occurred in two families and the close contacts in a county of Baotou city in Inner Mongolia Autonomous Region. Descriptive statistical analysis on epidemiological data was conducted. Results: The infection source of the COVID-19 cases in the two families was a man who had living history in Wuhan. After his return, his parents were infected by him. A few days later, the members of a neighbor family were found to be infected, and relatives of this family were also infected after dining together repeatedly. Finally, ten confirmed cases and three suspected cases of COVID-19 were detected in the two families. Conclusions: Human-to-human transmission of COVID-19 can occur not only in a family but also in neighborhoods. The cases in two families had close relationship, indicating the necessity to strengthen the health education about COVID-19 prevention and control and the management of groups at high risk to reduce the incidence of COVID-19 in families and neighborhoods.

Abstract
Objective: To understand the history, current situation and trends of intensive care unit (ICU) of pediatrics in China over the past 30 years. Methods: The results of the cross-sectional investigation on the status of ICU of pediatrics in 2014 were compared with those in 1993, 2001 and 2009. The main measurements were the number of participated provinces and hospitals, the availability of equipment, staffing, and medical technologies, the major diseases and the source of the patients. Besides, the equipment allocation and technology implementation in 2014 were compared with the standards in the "recommendations on grading construction and management of children's intensive care unit in China" published in 2016. Results: The contents of the four surveys were slightly different, with only a few measurements not documented in one or more surveys. (1) The number of provinces and hospitals involved in the four surveys were 20 hospitals in 14 provinces in year 1993, 27 hospitals in 17 provinces in year 2001, 33 hospitals in 25 provinces in year 2009 and 108 hospitals in 25 provinces in year 2014. (2) In 1993, 2001, 2009 and 2014, the ratio of doctors/beds were 0.7∶1,0.8∶1, (0.4-0.5) ∶1 and 0.5∶1, and the ratio of nurses/beds were 1.1∶1,1.4∶1, (1.1-1.7) ∶1 and 1.3∶1, respectively. (3) Regarding the equipment availability, in 1993, 2001, 2009, and 2014, the numbers of monitors were 0.3/ICU, 0.3/bed, 1.1-1.4/bed and 1.0/bed; the numbers of invasive ventilators were 0.4/bed, 0.5/bed, 0.6/bed and 0.4/bed, respectively. In 2001, 2009 and 2014, there were 60.0%, 100.0% (33/33) and 88.0% (95/108) of the participating ICU equipped with blood gas analyzer, and 70.0%, 93.9% (31/33) and 90.7% (98/108) with bedside X-ray machines, respectively. In 2009 and 2014, 69.7% (23/33) and 92.6% (100/108) ICU were equipped with non-invasive ventilators respectively. In 2014, 10.2% (11/108) ICU were equipped with extracorporeal membrane oxygenation (ECMO) equipment and 45.4% (49/108) ICU with bedside continuous blood purification equipment. In 1993, 2001 and 2014, the numbers of infusion pump were 0.5/ICU, 1.1/bed and 1.7/bed, respectively. (4) Regarding the conducted medical technology, in 2014, invasive mechanical ventilation was used in 100% (108/108) ICU, and non-invasive ventilation in 89.8% (97/108) ICU. High frequency ventilation was used in 78.8% (26/33) and 38.0% (41/108) ICU in 2009 and 2014 respectively. Blood purification was used in 22.0%, 69.7% (23/33) and 47.2% (51/108) ICU, and the application of surfactant was in 48.0%, 97.0% (32/33) and 24.1% (26/108) ICU in 2001, 2009 and 2014, respectively. Nitric oxide inhalation (iNO) was used in 24.0% and 9.3% (10/108) in 2001 and 2014 respectively. ECMO was used in 6 and 7 hospitals in 2009 and 2014 respectively. (5) Compared with the criteria in the "recommendations on grading construction and management of children's intensive care units in China" in 2016, only the availability of monitors and conventional mechanical ventilation in 2014 met the standards.The original data in 2001 was not shown due to the lack of absolute values. Conclusions: The number of ICU of pediatrics and its beds in China increased significantly from 1993 to 2014, as well as the equipment availability and the conducted medical technology. But the status in 2014 was still far behind the recommendations in 2016, with a significant shortage of professional staff.

Abstract
Objective: To investigate the feasibility, efficacy and safety of endovascular reconstruction of the carotid artery with severe stenosis and extracranial distortion under proximal protection. Methods: A retrospective analysis of 21 patients with severe carotid stenosis and extracranial distortion who were admitted to the Second Affiliated Hospital of Soochow University between January 2011 and August 2017, of which 16 patients were symptomatic stenosis with acute ischemic stroke. All the patients were treated with carotid artery stenting under (CAS) proximal protection technique, and assessed with the National Institutes of Health Stroke Scale (NIHSS) before the treatment and hospital discharge. The clinical outcome and vascular morphology were followed-up regularly after the treatment. Results: Twenty-one patients were successfully completed the CAS procedure under the proximal protection technique, the average blocking time was 241.0 (232.5-261.0) seconds. Nine patients received 1block attempt, 6 patients received 2 block attempts, and the other 6 patients received 3 block attempts. Three patients experienced transient ischemic attack (TIA) during the procedure, the maximum duration of TIA was 10 minutes. In 16 patients with symptomatic stenosis, there were no significant differences in NIHSS score before CAS procedure and hospital discharge (P>0.05). The residual stenosis rate of the carotid artery after stenting was(13±6)%, compared with preoperative (87±16)%, which appeared a significant difference (t=19.948, P<0.05). All the patients had no adverse events such as myocardial infarction, recurrent ischemic stroke and death in the follow-up period. Restenosis was assessed in 6 patients by DSA or CTA and no restenosis was found. Conclusion: Endovascular reconstruction of the carotid artery with severe stenosis and extracranial distortion under proximal protection technique has been proven as a safe and effective therapy.

Circular RNA hsa_circ_0000523 regulates the proliferation and apoptosis of colorectal cancer cells as miRNA sponge. ACTA ACUST UNITED AC 2018; 51:e7811. [PMID: 30403259 PMCID: PMC6233523 DOI: 10.1590/1414-431x20187811] [Citation(s) in RCA: 60] [Impact Index Per Article: 10.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/17/2018] [Accepted: 09/04/2018] [Indexed: 12/14/2022]
Abstract
Among the novel class of endogenous long non-coding RNAs, circular RNA (circRNA) is known as a key regulator in the development and progression of different cancers. Its function and mechanism in the tumorigenesis of colorectal cancer, however, has not been well studied. This study thus aimed to investigate potential regulation of colorectal cancer by circRNAs and the corresponding regulatory mechanism. We demonstrated that the expression of circRNA hsa_circ_0000523 (also known as circ_006229) was down-regulated in different colorectal cancer cell lines. It was also found that interference of hsa_circ_0000523 induced proliferation and suppressed apoptosis of colorectal cancer cells, the proliferation rate of which was reduced by the overexpression of hsa_circ_0000523. In addition, we found that miR-31 could recognize hsa_circ_0000523 sequence and that it acted as a "sponge" of miR-31, indirectly regulating Wnt/β-catenin signaling pathway, which was involved in the progression of colorectal cancer. The results suggested that the expression of hsa_circ_0000523 correlated to the tumorigenesis of colorectal cancer cells. In addition, as a sponge of miR-31, the low level of hsa_circ_0000523 led to activation of Wnt/β-catenin signaling pathway, inducing the subsequent progress of colorectal cancer.

Abstract
Objective: To investigate the effect of intrauterine intervention on severe primary fetal hydrothorax. Methods: Twelve cases with severe fetal primary hydrothorax who underwent prenatal intervention from January 2014 to December 2017 in Guangdong Women and Children Hospital were retrospectively reviewed. Results: The median gestational age of prenatal diagnosis was 30.8 weeks (24.0-33.0 weeks) . All cases were excluded congenital chromosomal abnormalities by prenatal diagnosis, and had no complications of pregnancy during prenatal diagnosis and had hydrothorax. Three cases (3/12) were right hydrothorax, the other 9 cases (9/12) were bilateral. Thoracoamniotic shunting was performed in 7 cases (7/12) . Thoracentesis was performed in 5 cases (5/12) , and the hydrothorax reappeared soon after operation in 4 cases, shunt placement was performed again. The hydrothorax was dissolved in 2 cases, released in 6 cases.Tube falling off occurred in 1 case,treatment was abandoned in 1 case and intrauterine fetal death happened in 1 case, and 1 case wasn't rechecked by ultrasonic due to premature birth following thoracentesis. In 10 cases who had deliveries, 5 newborns (5/10) were premature, 6 newborns (6/10) underwent assisted mechanical ventilation, 8 newborns (8/10) underwent thoracic close drainage, all of them were discharged when hydrothorax resolved. Conclusions: Antenatal intervention may improve the chance of survival in severe primary fetal hydrothorax. Thoracoamniotic shunting is the first-choice for the primary severe fetal hydrothorax.

Abstract
Objective: To explore the radiological, pathological features and clinical characteristics of neuroendocrine prostate cancer patients(NEPC). Methods: The clinical characteristics and pathology data of 13 neuroendocrine prostate cancer patients treated in the Affiliated Hospital of Tianjin Medical University from January 2004 to January 2015 were analyzed retrospectively. Results: Of all 13 patients, three cases were primally diagnosed small cell cancer, and 10 cases were translated to neuroendocrine type from adenocarcinoma after endocrine therapy. Frequent urination, urgency, nocturia, and dysuria were main symptoms. Serum prostate-specific antigen (PSA) was (14.5±3.2)μg/L; the volume of prostate was enlarged, mean volume, range 28-176(45±4)ml. The lesion was moderately low signal intensity in T(2)WI, while slightly higher signal in DWI. Signal characteristic of dynamic enhanced MRI was "fast in fast out" . The expression of Synaptophysin, Chromogranin A , CD56 and Ki-67 in NEPC were highly expressed by immunohistochemistry analysis. Among them, five patients accepted intravenous chemotherapy, two cases received external radiation therapy, three cases received cryoablation and three cases received palliative therapy. Median survival time in all 13 patients was 10 months, while median survival time in patients treated by chemotherapy was 16 months . Conclusion: NEPC is a highly aggressive subtype of prostate cancer characterized by rapid disease progression, lack of treatment and worse prognosis. Therefore, patients with NEPC may benefit from early diagnosis and comprehensive treatment with chemotherapy.

Abstract
Polylactic acid (PLA) bubbles that can act both as ultrasound contrast agents and drug carriers have the disadvantage of low encapsulation efficiency and do not allow effective extravasation into the tumor tissue. In this regard, PLA and lecithin are considered drug carriers. The present study used a modified ultrasonic double emulsion-solvent evaporation technology in order to prepare paclitaxel-loaded PLA-lecithin nanobubbles. X-ray diffraction analysis (XRD) was used to investigate the state of the drug in the bubbles, whereas the tumor weight and the inhibition rate of tumor bearing mice in the ultrasound-mediated function were further examined. The results indicated that the nanobubbles prepared with a mass ratio of PLA and lecithin at 50:250 were characterized as inner hollow. The size of these particles was approximately 615 nm, and the drug loading and encapsulation reached 8.34±0.67% and 91.42±5.48%, respectively. Paclitaxel was distributed in the shell of the bubbles in an amorphous state, and the in vitro drug release was characterized by sustained release, zero release and ultrasound mediated drug release. The injection of H22 hematoma-bearing mice with ultrasound-mediated drug-loaded PLA-lecithin nano-scaled bubbles could reduce the toxicity and increase the antitumor efficacy compared with paclitaxel.

Abstract
Objective: To investigate the current application status of continuous blood purification (CBP) technology and equipment in pediatric intensive care unit (PICU) in China. Methods: A cross-sectional survey was conducted to understand the current popularization of CBP technology and equipment, the management of CBP equipment and consumables, and the application of CBP in different diseases. A questionnaire named Application Status of Continuous Blood Purification Technology was applied. Children's hospitals and polyclinic hospitals with the pediatric qualification (pediatric emergency or critical care unit members of Chinese Medical Association and Chinese Medical Doctor Association) were selected. Results: From December 2016 to February 2017, 53 hospitals completed the questionnaire, including 7 in northeast, 6 in north China, 16 in east China, 9 in south China, 5 in central China, 4 in the northwest, and 6 in the southwest region. Continuous renal replacement therapy (CRRT), the most widely used technology, was carried out in 51 hospitals. Other technologies were peritoneal dialysis (IPD) (n=37), artificial liver support (ALSS) (n=26) and blood adsorption (PA) (n=13). There were 107 CBP machines in the 51 hospitals used CBP technology, with an average of 2.10/hospital. In 36 hospitals CBP machines were managed independently by PICU (70%). Hospitals made their own displacement liquid (n=40, 78%), or purchased displacement liquid (n=11, 22%). Hospitals prepared dialysate on their own (n=38, 75%), or purchased dialysate (n=13 hospitals, 25%). In 46 (90%) hospitals, hemodialysis catheter was placed independently by PICU doctors. The routine operation and maintenance of CBP were mainly completed by the PICU nurses in 36 hospitals (71%). There were 39 hospitals (76%) where professional nurses manage and maintain CBP. Puncture sites were femoral vein (n=26, 51%), internal jugular vein (n=21, 41%) and venae subclavia (n=4, 8%). Forty-two hospitals (82%) selected B-mode ultrasound positioning and guidance when performing internal jugular vein puncture. A total of 40 (78%) hospitals have developed post dilution and combined dilution techniques during the implementation of CBP. The most common indications of CBP technology were different in different regions. They were sepsis in northeast (24.0%, 243/1 011) and east China region (32.0%, 982/3 069), multiple organ dysfunction syndrome in south China (29.2%, 444/1 520), north China (15.8%, 126/796), and southwest region (30.1%, 460/1 526), drug poisoning in central China region (21.6%, 325/1 506), and renal failure in northwest region (53.0%, 44/83). Conclusions: CBP technology is widely used in the field of pediatric severe diseases in China. The eastern regions possess more CBP equipment than the western regions. CBP is widely used in the treatment of sepsis.

Abstract
Objective The objective of the present study is to evaluate the current status of care and charges of acute ischaemic stroke in a university teaching hospital in China, and to identify the main determinants of such charges. Methods Acute ischaemic stroke patients from July 2009 to June 2010 were considered. We examined demographic data, clinical data, hospital care and outcomes at discharge and hospital charges retrospectively. The influence of medical factors on total charges was analyzed. Results The mean initial National Institutes of Health Stroke Scale score of all acute ischaemic stroke patients was 7.2 points. Thirteen percents were total anterior circulation syndrome, 20% were partial anterior circulation syndrome, 7% were posterior circulation syndrome and 60% were lacunar syndrome. The mean hospital length of stay (LOS) was 8.5 days. All patients underwent neuroimaging studies, 2% of whom received thrombolysis, 93% received traditional Chinese medicine injection, 83% received antiplatelet and 6% received anticoagulation therapy, only 29% received in-hospital rehabilitation. The mean hospital charges per patient was ¥9230.2 (US$1357.3), of which 56.2% was attributed to the charges for medications, 13.4% for imaging studies, 12.1% for laboratory examinations. Total hospital charges were correlated strongly with LOS, admission to care unit, and computed tomography angiography or digital subtraction angiography of the brain. Conclusions Total hospital charges correlates significantly with hospital LOS, admission to care unit, investigation with computed tomography angiography or digital subtraction angiography of the brain, while clinical syndromes do not influence total charges independently. The cost of drug is the largest portion of the mean hospital charge. A treatment protocol in acute ischaemic stroke might optimise cost. (Hong Kong j.emerg.med. 2011;18:383-390)

Abstract
Objective: To analyze the clinical characteristics of community-acquired pneumonia (CAP) in children under five years of age and analyze the safety and efficiency of nasal continuous positive airway pressure (NCPAP) ventilation for CAP in this population. Method: This was a prospective multicenter study. Children who were admitted to these six centers with CAP and met the NCPAP ventilation indications, aged from 29 d to 5 years, were continuously included during November 2013 to October 2015. The baseline data were collected and NCPAP ventilation were then followed up by operation standards, and the vital signs and arterial blood gas change at special time points were observed and recorded. Any side effect associated with NCPAP were recorded. For categorical variables, comparisons were performed using Fisher test. Rank-sum test and t test were performed respectively for abnormal and normal distribution continuous variables. The variables pre-NCPAP and post-NCPAP were analyzed by repeated measures ANOVA analysis. Result: Totally 145 children were included, and 13 children were excluded due to incomplete data. One hundred and two children(77.3%)were ≤12 months; 91 children (68.9%) were from rural area. NCPAP ventilation was effective in 123 children, with a response rate of 93.2%, were all discharged with a better condition; it was ineffective in 9 children(6.8%), and they were all intubated and went on mechanical ventilation, 5 were discharged with a better condition, and 4 died after gaving up treatment. The gender, age, body weight, residence, main symptoms, main signs, imaging diagnosis, medications, partial pressure of oxygen(PaO(2)), breath and heart rate before NCPAP treatment of two groups had no significant differences(allP>0.05). The rates of combining underlying diseases, trouble with feeding and cyanosis, and the partial pressure of carbon dioxide(PaCO(2) ) before NCPAP ventilation were higher in NCPAP ineffective group ((59±11 )vs.( 49±11) mmHg, 1 mmHg=0.133 kPa, t=-2.597, P=0.028); while the PaO(2)/fraction of inspiration O(2) (FiO(2) ) before NCPAP was lower((150±37) vs. (207±63) mmHg, t=2.697, P=0.008). The breathing, heart rate and PaCO(2) of NCPAP effective group decreased significantly, while the PaO(2) and PaO(2)/FiO(2) increased significantly after 2, 8, 24 h of NCPAP ventilation(all P=0.000). PaCO(2) in children with hypercapnia before NCPAP ventilation in NCPAP effective group decreased significantly ((48±9), (47±12), (45±11)vs.(58±7)mmHg, all P=0.000). All children tolerated well to NCPAP ventilation, and there were no severe side effects or complications associated with NCPAP ventilation. Conclusion: NCPAP ventilation is safe and effectively improved the oxygenation and hypercapnia in infants with CAP. But it may not work well in children with underlying diseases, manifest as difficulty in feeding/cyanosis and extremely high PaCO(2) or low PaO(2)/FiO(2), and they may need early intubation.

Abstract
Objective: To investigate the effect of obstructive sleep apnea (OSA) on sleep architecture in acute ischemic stroke (AIS) patients. Methods: Seventy AIS patients with polysomnography examination from June 2014 to April 2016 were included in the Second Affiliated Hospital of Soochow University. Twenty-seven healthy controls during the same period were chosen as control group. According to apnea-hypopnea index (AHI), AIS patients were divided into AIS group (AHI<5/h) and AIS+ OSA group (AHI≥5/h). Their general conditions, Neurological function defect (national institutes of health stroke scale, NIHSS) on admission and at discharge and self-care ability (modified Rankin Scale, mRS) at discharge and 3 months later (mRS score <2 reflected good prognosis, and mRS score≥2 reflected unfavorable prognosis) were collected. Results: Fifty-two patients (74.3%) had OSA in total seventy AIS patients. Total sleep time (TST) was significantly shorter and sleep efficiency (SE) was lower in AIS group than the control group (P=0.007, 0.008, respectively). AIS+ OSA group had longer non-rapid eye movement (NREM)1 than control group [24.9(21.3) vs 14.3(10.6), P=0.044]. Compared with AIS group, AIS+ OSA group had shorter NREM3 [13.0(13.2) vs 19.6(12.8), P=0.039]. There was no significant difference between the infarct location of AIS group and AIS+ OSA group. However, AIS+ OSA group had higher mRS score observed at 3 months through follow-up visit than AIS group (P=0.027). Spearman correlation analysis showed a positive correlation between unfavorable prognosis of stroke at 3 months and atrial fibrillation, the oxygen desaturation index (ODI), percentage of oxygen saturation <90% of total recording time (TS90%), AHI, the longest time of apnea and hypopnea, respiratory related microarousal and NIHSS, while a negative correlation between unfavorable prognosis of stroke and NREM3, lowest nocturnal oxygen saturation (L-SaO(2)). On Logistic analysis, the unfavorable prognosis was independently predicted by AHI and NIHSS. Conclusions: Sleep architecture of cerebral infarction patients are disturbed with its characteristic of shorter total sleep time and lower sleep efficiency. Cerebral infarction patients with OSA have longer NREM1 and shorter NREM3.

Abstract
Objective: To identify the expression of apoptosis-associated genes of high- intensity focused ultrasound(HIFU) in xenograft with human pancreatic cancer. Methods: Mice implated with human pancreatic cancer cells (YY-1) were divided into HIFU group or control group. Tumor cell apoptosis was verified by TUNEL. The expression of the apoptosis-associated genes was analyzed by Agilent Human Gene Expression. Selected genes was validated by quantitative real-time PCR(RT-PCR)and Western blot. Results: The rate of tumor cell apoptosis in HIFU group was higher than that of control group at 7, 14 days after HIFU treatment ((63.6%±15.2%)vs (19.0%±2.4%), P<0.01)and ((41.4%±7.3%)vs(18.0%±2.4%), P<0.01). Gene expression profiling revealed a total of 69 differentially expressed genes in related to apoptosis pathway, among which 44 genes were up-regulated, and 25 genes down-regulated. The RT-PCR results of selected 4 genes were consistent with those of gene expression profiling. The results of Western blot analysis at 7, 14 days after HIFU treatment showed that the expressions level of Bax protein in HIFU group was greater that of in control group ((0.39±0.11)vs (0.20±0.09), P<0.05)and ((0.46±0.12)vs(0.24±0.10), P<0.05), while the expressions level of Bcl-2 protein in HIFU group was lower than that of in control group ((0.68±0.14)vs(1.56±0.21), P<0.05)and((0.51±0.16)vs(1.57±0.22), P<0.05). Conclusions: HIFU could induce apoptosis and results in dramatic changes in gene expression, indicating that multiple pathways are involved. Although intrinsic pathway might be predominantly involved in HIFU-elicited apoptosis, further research is needed to clarify the detailed mechanisms.

OBJECTIVE To explore the clinical characteristics and prognostic factors in patients with Parkinson's disease (PD) and excessive daytime sleepiness (EDS) and to identify whether EDS could influence the sleep architecture and sleep apnea-related parameters. METHODS A total of 130 PD patients were eligible and enrolled in the study.By the Epworth sleepiness scale (ESS), patients were divided into the EDS group (ESS≥10) with 61 patients and the non-EDS group (ESS<10) with 69 patients.All underwent a video-polysomnography (PSG). Clinical characteristics were mainly evaluated by the unified Parkinson's disease rating scale (UPDRS) and the Hoehn-Yahr(H-Y)stage.while other related scales were applied for evaluating depression, cognitive function, quality of sleep and quality of life. RESULTS A total of 61 patients (46.92%) were diagnosed as EDS (ESS≥10). Compared to the non-EDS group, the EDS group had significantly higher score of HAMD, UPDRSⅠand UPDRSⅡ, and significantly lower score of MoCA and PDQ (all P<0.05). Non-conditional logistic regression analysis showed that the scores of HAMD and UPDRSⅠ were the main prognostic factors for EDS.Significantly decreased sleep latency (SL) was found in the EDS group by PSG (P=0.008). The score of ESS was showed to be correlated with the scores of HAMD, MoCA, UPDRSⅠ, UPDRSⅡ, PDQ and SL. CONCLUSIONS PD patients with EDS have more severe depression and cognitive dysfunction and worse quality of life.Sleep structure is altered in those patients with decreased sleep latency.Mental status is closely associated with EDS, but not sleep apnea.

Abstract
Objective: To investigate the relation between cognition and serum calcium in the patients with Parkinson's disease (PD), analyze the related factors of cognition, and evaluate the correlation of serum calcium with specific cognitive domains. Methods: A total of 77 patients with Parkinson's disease who was hospitalized in the Second Affiliated Hospital of Soochow University, from Dce 2013 to May 2015 were subjected to the cognitive, motor and depression function assessment, and the fasting blood calcium samples were collected from the PD patients and 75 normal control subjects. According to cognitive function, PD patients were divided into dementia group and without dementia group. Then the serum calcium levels of three groups and the related factors of the cognitive were analyzed by multiple linear regression. Results: (1) The level of serum calcium in PD group with dementia (2.21±0.09) mmol/L was significantly lower than the normal control group (2.30±0.09)mmol/L (P<0.001), and there was no difference between the level of serum calcium in PD group without dementia (2.27±0.13 mmol/L) and normal control group (P=0.144). The level of serum calcium in PD group with dementia was lower than PD group without dementia, and there was marked statistical significance (P=0.023). (2) In PD patients, the cognitive scores correlated with serum calcium levels, education, H-Y stages and Unified Parkinson's Disease Rating Scale (UPDRS) Ⅲ scores (P<0.05), but didn't with gender, age, disease duration, depression levels, Body Mass Index (BMI) and total equivalent levodopa doses (P>0.05). (3) In PD patients, serum calcium level correlated with the visuospatial and executive capability, calculation ability, language ability (P1=0.004; P2=0.027; P3=0.021). Conclusions: (1) There is correlation between the serum calcium and the cognitive impairment. Lower serum calcium level predicts worse cognitive scores. (2) In PD patients, the change of the cognitive function is affected by their education, H-Y stages and UPDRSⅢ scores. (3) The serum calcium level of PD patients closely relates to the cognitive domain of the visuospatial and executive capability, calculation ability, and language ability.

Abstract
OBJECTIVE To observe the difference of the human telomeres RNA component (hTERC) genes' amplification in the cervical tissue by applying the environment-friendly fixative poly hydroxy acrylic acid and the transparent dewaxing solution Van-clear separately or jointly to replace the traditional fixative 4% (volume fraction) neutral buffered formalin and the conventional transparent dewaxing solution xylene in the use of fluorescence in situ hybridization (FISH) for detection. METHODS In the study, 255 cases of cervical tissue specimens submitted by the Department of Gynecology in Zhongshan Boai Hosipital were collected from Mar. 2013 to Apr. 2015. Four samples were taken from the same lesion site. All the cases were divided into 4 groups and named group A, B, C, and D. Group A used 4% neutral buffered formalin fixed and xylene dewaxing to make slices. Group B used poly hydroxy acrylic fixed and xylene dewaxing to make slices. Group C used 4% neutral buffered formalin fixed and Van-clear transparent to make slices. Group D used poly hydroxy acrylic fixed and Van-clear transparent dewaxing to make slices. The amplification of hTERC genes in the four groups of cervical specimens was also detected by FISH technique. RESULTS When the hTERC genes were detected by FISH method under the fluorescence microscope, it was obvious that the tissue profile and the background of group A, B, C and D were all clear. The probe was fixed in the accurate position so that the bright red or green fluorescence signals were easily found in these four groups. Compared with the positive rate of group A, there was no statistical significance in that of group B, C and D (P>0.05). At the same time, the coincidence rate of the FISH results was high, which showed that the new environment-friendly reagent had no significant difference in the detection of cervical hTERC genes by FISH technique. CONCLUSION It is possible for the environment-friendly reagent poly hydroxy acrylic acid and Van-clear to replace 4% neutral buffered formalin and xylene separately or jointly to detect the cervical hTERC genes by adopting FISH technique.

Abstract
OBJECTIVE To investigate the effects of transcutaneous electrical nerve stimulation (TENS) through acupoints on the intraocular pressure (IOP) in patients with glaucoma. METHODS A single-blinded, randomized experimental design study was conducted. Patients from the North of Taipei Ophthalmology outpatient department diagnosed with intraocular hypertension were selected and were further enrolled if they met the research subject criteria. The patients who met all criteria, and who met no exclusion criteria became the participants. Participants were randomly assigned into the treated group, wherein the TENS electrodes (Qing Ming Medical Device Co., Ltd., New Taipei City, China) were applied with direct current (DC) on the acupoints Pucan (BL 61) and Shenmai (BL 62) for 20 min. The control group received no TENS electrode treatments. Measurements of IOP were taken four times using a pneumotonometer (Clinico Co., Ltd., New Taipei City, China), before, immediately after, 30 min after, and 60 min after TENS electrode treatments. RESULTS Eighty-two participants completed the experiment. IOP decreased more in the group treated with DC (P < 0.01) than in the control group. The IOPs were not affected by the age of the patients and their usage of medications. CONCLUSION TENS of acupoints of Pucan (BL 61) and Shenmai (BL 62) could significantly reduce the IOP in patients with glaucoma.

Abstract
The present study showed that oral mushroom beta-glucan treatment significantly increased IFN-γ mRNA expression but significantly reduced COX-2 mRNA expression within the lung. For LLC tumor model, oral Ganoderma lucidum or Antrodia camphorata polysaccharides treatments significantly reduced TGF-β production in serum. In addition, IL-12 and IFN-γ mRNA expression were significantly increased, but IL-6, IL-10, COX-2, and TGF-β mRNA expression were substantially following oral mushroom polysaccharides treatments. The study highlights the efficacious effect of mushroom polysaccharides for ameliorating the immune suppression in the tumor microenvironment. Increased M1 phenotype of tumor-associated macrophages and attenuated M2 phenotype of tumor-associated macrophages could be achieved by ingesting mushroom polysaccharides.

Abstract
BACKGROUND Dementia is a costly disease. People with dementia, their families, and their friends are affected on personal, emotional, and financial levels. Prior work has shown that the "Partners in Dementia Care" (PDC) intervention addresses unmet needs and improves psychosocial outcomes and satisfaction with care. OBJECTIVE We examined whether PDC reduced direct Veterans Health Administration (VHA) health care costs compared with usual care. DESIGN This study was a cost analysis of the PDC intervention in a 30-month trial involving five VHA medical centers. PARTICIPANTS Study subjects were veterans (N = 434) 50 years of age and older with dementia and their caregivers at two intervention (N = 269) and three comparison sites (N = 165). INTERVENTIONS PDC is a telephone-based care coordination and support service for veterans with dementia and their caregivers, delivered through partnerships between VHA medical centers and local Alzheimer's Association chapters. MAIN MEASURES We tested for differences in total VHA health care costs, including hospital, emergency department, nursing home, outpatient, and pharmacy costs, as well as program costs for intervention participants. Covariates included caregiver reports of veterans' cognitive impairment, behavior problems, and personal care dependencies. We used linear mixed model regression to model change in log total cost post-baseline over a 1-year follow-up period. KEY RESULTS Intervention participants showed higher VHA costs than usual-care participants both before and after the intervention but did not differ significantly regarding change in log costs from pre- to post-baseline periods. Pre-baseline log cost (p ≤ 0.001), baseline cognitive impairment (p ≤ 0.05), number of personal care dependencies (p ≤ 0.01), and VA service priority (p ≤ 0.01) all predicted change in log total cost. CONCLUSIONS These analyses show that PDC meets veterans' needs without significantly increasing VHA health care costs. PDC addresses the priority area of care coordination in the National Plan to Address Alzheimer's Disease, offering a low-cost, structured, protocol-driven, evidence-based method for effectively delivering care coordination.

Role of mitochondrial ATP-sensitive potassium channel-mediated PKC-ε in delayed protection against myocardial ischemia/reperfusion injury in isolated hearts of sevoflurane-preconditioned rats. ACTA ACUST UNITED AC 2015; 48:528-36. [PMID: 25831209 PMCID: PMC4470312 DOI: 10.1590/1414-431x20143876] [Citation(s) in RCA: 20] [Impact Index Per Article: 2.2] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/27/2014] [Accepted: 10/07/2014] [Indexed: 01/23/2023]
Abstract
This study aimed to determine the role of mitochondrial adenosine
triphosphate-sensitive potassium (mitoKATP) channels and protein kinase C
(PKC)-ε in the delayed protective effects of sevoflurane preconditioning using
Langendorff isolated heart perfusion models. Fifty-four isolated perfused rat hearts
were randomly divided into 6 groups (n=9). The rats were exposed for 60 min to 2.5%
sevoflurane (the second window of protection group, SWOP group) or 33% oxygen
inhalation (I/R group) 24 h before coronary occlusion. The control group (CON) and
the sevoflurane group (SEVO) group were exposed to 33% oxygen and 2.5% sevoflurane
for 60 min, respectively, without coronary occlusion. The mitoKATP channel
inhibitor 5-hydroxydecanoate (5-HD) was given 30 min before sevoflurane
preconditioning (5-HD+SWOP group). Cardiac function indices, infarct sizes, serum
cardiac troponin I (cTnI) concentrations, and the expression levels of phosphorylated
PKC-ε (p-PKC-ε) and caspase-8 were measured. Cardiac function was unchanged, p-PKC-ε
expression was upregulated, caspase-8 expression was downregulated, cTnI
concentrations were decreased, and the infarcts were significantly smaller
(P<0.05) in the SWOP group compared with the I/R group. Cardiac function was
worse, p-PKC-ε expression was downregulated, caspase-8 expression was upregulated,
cTnI concentration was increased and infarcts were larger in the 5-HD+SWOP group
(P<0.05) compared with the SWOP group. The results suggest that
mitoKATP channels are involved in the myocardial protective effects of
sevoflurane in preconditioning against I/R injury, by regulating PKC-ε
phosphorylation before ischemia, and by downregulating caspase-8 during
reperfusion.

Abstract
Recently studies performed on mushroom isolated polysaccharides demonstrated that β -(1,3)-glucan may affect the balance of Th1/Th2 cell response. Using ovalbumin (OVA) as a hypersensitivity inducer, we evaluated the ability of mushroom beta-glucan (MBG) in modulating Th1/Th2 cell responses in B6 mice. As compared to the control group, administration of MBG resulted in an increase of phagocytic activities, Th1 cytokine productions, immunoglobulins including IgG2A and IgA, and a significant expression of the splenic surface markers including CD3, CD4, CD8, and F4/80. In contrast, administration of MBG has significantly suppressed IgE and IgG1 levels and Th2 cytokines including IL-4, IL-5, and IL-6. Histopathological observation of MBG-treated followed by OVA-treated mice showed less filtration of eosinophil in pulmonary tissue sections. Our data suggested that administration of MBG treatments alters the natural course of the IgE-mediated hypersensitivities. In this investigation, we realize the mushroom beta glucan alter the Th2 response toward the Th1 in the allergic, resulting in a reduction in IgE productions which played a substantive role in reducing the severity of IgE-mediated hypersensitivity.

Abstract
Coptidis Rhizoma (Coptis chinensis) has been reported to have antioxidative effect on hemolysis of erythrocytes induced by acetylphenylhydrazine in mice and rats. However, the ability of Coptidis Rhizoma to protect structure and function of erythrocytes membrane and morphology of erythrocytes against oxidative damage remains unknown. In this study, we undertook a characterization of antioxidative activity in erythrocytes membrane of Coptidis Rhizoma using an in vivo model of acetylphenylhydrazine-induced mice together with in vitro studies with 2,2-azo-bis (2-amidinopropane) dihydrochloride-induced erythrocytes for further morphology characterization. Acetylphenylhydrazine-induced mice were treated intragastrically with Coptidis Rhizoma at doses of 0.3, 0.6, and 1.2 g/kg per day for 3 days and at the dose of 0.6 and 1.2 g/kg it showed that there was an increasing trend in membranes cytoskeletal proteins of band I-IV, especially a significant upregulation in band II. Significant increase in phosphatidylserine and phosphatidylcholine content at the dose of 1.2 g/kg Coptidis Rhizoma was obsereved. At all doses of Coptidis Rhizoma, the declined membrane fluidity of acetylphenylhydrazine-induced mice was significantly increased. In addition, at the dose of 1.2 g/kg Coptidis Rhizoma treatment showed a significant increase in Ca2+/Mg2+-ATPase activity and there was an increasing trend in the activity of Na+/K+-ATPase. In vitro, Coptidis Rhizoma protected erythrocytes from 2,2-azo-bis (2-amidinopropane) dihydrochloride-induced hemolysis in a dose-dependent manner at concentrations of 0.25-1.5 mg/ml, and also significantly inhibited the 2,2-azo-bis (2-amidinopropane) dihydrochloride-induced morphological alterations in mice erythrocytes. These results demonstrate that Coptidis Rhizoma is capable of protecting erythrocytes against oxidative damage probably by acting as an antioxidant and maintaining membrane integrity.

Abstract
Succinoylation and benzoylation of ball-milled eucalyptus wood using succinic anhydride and benzoyl chloride as acylating reagent, respectively, were investigated at room temperature using dimethyl sulfoxide/N-methylimidazole (DMSO/NMI) as reaction medium without additional catalysts. The effects of the corresponding acylating reagent dosage (1-5:1 for succinoylation and 0.5-5:1 for benzoylation) and reaction time (0.35-5h for succinoylation and 0.5-3h for benzoylation) on the extent of acylation, measured by weight percent gain (WPG), were studied. WPG of succinoylation and benzoylation was in the range of 70.8-144.7% and 17.3-43.1%, respectively. The efficiency of acylation at room temperature significantly increased in DMSO/NMI compared with ionic liquid 1-butyl-3-methylimidazolium chloride because of the role of NMI as solvent, base and catalyst. Fourier transform infrared (FT-IR), and solid-state cross-polarization/magic-angle spinning (CP/MAS) (13)C nuclear magnetic resonance (NMR) spectroscopy studies provided evidence for the occurrence of succinoylation and benzoylation reactions and the attachment of functional groups via ester bonds.

Abstract
Porokeratosis is a rare disorder of epidermal keratinization that is characterized by the presence of a border called the cornoid lamella. Disseminated superficial porokeratosis (DSP) is a subtype of porokeratosis, which is inherited as an autosomal trait. The first locus for DSP was localized to chromosome 18p11.3, but no causative gene has yet been identified. In this study, we recruited and analysed a large six-generation Chinese family with autosomal dominant DSP. The genome-wide screening identified a maximum two-point LOD score of 3.06 at θ = 0.00 with the microsatellite marker D12S78. Fine mapping and haplotype analysis defined a critical region of 38 Mb between D12S326 and D12S79 on chromosome 12q21.2-24.21, which is a probable second locus identified for DSP (DSP2). We sequenced 50 candidate genes in this region, but no causative mutation was found. This study provides a map location for isolation of a gene causing DSP.

Abstract
Acute p.o. administration of 99.5% ethanol (0.1 ml) to fasted mice produced heart toxicity. Pretreatment with p.o. administration of tetramethylpyrazine (TMP) could prevent such toxicity effectively and dose-dependently. The maximal antioxidative effect against 99.5% ethanol-induced heart toxicity could be observed at 1 hour after TMP administration. In order to further investigate the heart protective mechanism of TMP, both lipid peroxidation level in vivo and superoxide scavenging activity were conducted. TMP exhibited a dose-dependently anti-lipid peroxidation effect in mice heart homogenate, and results indicated that 99.5% ethanol-induced intoxicated mice hearts have higher malonic dialdehyde (MDA) levels compared with those in TMP administrated mice hearts. These results suggest that the potentially heart protective mechanism of TMP could be contributed, at least in part, to its prominent anti-lipid peroxidation and anti-free radical formation effects, hence it could protect the heart from lipid peroxidation-induced heart toxicity.
