Relationship between plasma fluoride content, daily calcium intake and blood cell parameters in children and adolescents / 中华地方病学杂志

Objective:To investigate the relationship between plasma fluoride content, daily calcium intake and blood cell parameters in children and adolescents.Methods:This study was based on the National Health and Nutrition Examination Survey (NHANES) database of the United States from 2013 to 2016, with 3 684 children and adolescents aged 6 - 19 as the research subjects. Information on plasma fluoride content, daily calcium intake and blood cell parameters from the database were collected. Non-linear relationships between plasma fluoride content, daily calcium intake and blood cell parameters were analyzed using restricted cubic splines. If there was a non-linear relationship, the optimal inflection point was calculated using threshold/saturation effect analysis method. Subsequently, multiple linear regression models were used to analyze the associations among the three, and the modification effect of daily calcium intake (binary classification, stratified by median daily calcium intake) on the association between plasma fluoride content and blood cell parameters was analyzed.Results:There was no non-linear relationship between plasma fluoride content and white blood cell count, hemoglobin content and platelet count ( Pnon-linear > 0.05), but there was a non-linear relationship between plasma fluoride content and erythrocyte count and hematocrit ( Pnon-linear < 0.001). After adjusting for confounding factors, the optimal inflection points of the effects of plasma fluoride content on erythrocyte count and hematocrit were 0.54 and 0.31 μmol/L, respectively. There was no non-linear relationship between daily calcium intake and blood cell parameters ( Pnon-linear > 0.05). After adjusting for confounding factors, for every 1 μmol/L increase in plasma fluoride content, the white blood cell count increased by 0.49 × 10 9/L ( P = 0.009). There was a saturation effect in the association between plasma fluoride content, erythrocyte count and hematocrit: when plasma fluoride content was < 0.54 μmol/L, the erythrocyte count decreased by 0.46 × 10 12/L for every 1 μmol/L increase ( P < 0.001). When plasma fluoride content was < 0.31 μmol/L, the hematocrit decreased by 6.29% for every 1 μmol/L increase ( P = 0.006). The above associations were not statistically significant when plasma fluoride content was higher than the optimal inflection points ( P > 0.05). After stratification according to the median daily calcium intake, in the low-calcium group (daily calcium intake < 0.87 g), for every 1 μmol/L increase in plasma fluoride content, the white blood cell count increased by 0.77 × 10 9/L ( P = 0.001). When plasma fluoride content was < 0.54 μmol/L, the erythrocyte count decreased by 0.41 × 10 12/L for every 1 μmol/L increase ( P = 0.002). When plasma fluoride content was ≥0.54 μmol/L, erythrocyte count decreased by 0.47 × 10 12/L for every 1 μmol/L increase ( P < 0.001). When the plasma fluoride content was < 0.31 μmol/L, the hematocrit decreased by 8.29% for every 1 μmol/L increase ( P = 0.011). The above associations were not statistically significant in the high-calcium group (daily calcium intake ≥0.87 g, P > 0.05). There was an interaction of daily calcium intake and plasma fluoride content on platelet count ( Pinteraction = 0.070), as demonstrated by an increase in platelet count of 12.68 × 10 9/L ( P = 0.013) in the low-calcium group and a decrease in platelet count of 9.05 × 10 9/L ( P = 0.035) in the high-calcium group for every 1 μmol/L increase in plasma fluoride content. Conclusions:The blood cell parameters of children and adolescents are closely related to plasma fluoride content, but not directly related to daily calcium intake. However, the correlation between plasma fluoride content and blood cell parameters varies among different calcium intake populations, and daily calcium intake can modify the association between plasma fluoride content and platelet count.

Canagliflozin attenuates human podocyte injury through inhibiting reactive oxygen species/NOD-like receptor thermal protein domain associated protein 3 signaling pathway / 中华肾脏病杂志

Objective:To investigate the efficacy and mechanism of canagliflozin (Cana) in the treatment of high glucose-induced human podocyte (HPC) injury.Methods:The HPCs were divided into 5 groups: normal glucose group (NG group), mannitol group (MA group), high glucose group (HG group), Cana low dose (0.3 μmol/L) group and Cana high dose (1.0 μmol/L) group. Western blotting was used to examine the protein expressions of membrane-associated guanylate kinase inverted-2 (MAGI2), podocyte-associated protein nephrin, sodium-glucose transporter 2 (SGLT2), NOD-like receptor thermal protein domain associated protein 3 (NLRP3), apoptosis- associated speck-like protein containing a CARD (ASC), and cleaved-caspase1 in podocytes. Phalloidin staining of F-actin in podocytes was used to observe cytoskeletal injury. Intracellular reactive oxygen species (ROS) level of HPC was detected by the 2',7'-dichlorodihydrofluorescein diacetate (DCFH-DA) probe. Levels of interleukin (IL)-18 and IL-1β in culture medium of podocytes were detected by enzyme-linked immunosorbent assay (ELISA).Results:(1) Compared with the NG group, the protein expressions of MAGI2 and nephrin decreased (both P<0.01), the protein expression of SGLT2 increased ( P<0.01), the changes of cell morphology and cytoskeleton remodeling were obvious, intracellular ROS level increased ( P<0.01), while NLRP3, ASC and cleaved-caspase1 protein expressions decreased in the HG group (all P<0.01). The results of ELISA showed that IL-18 and IL-1β concentrations were higher in the HG group (both P<0.05). (2) Compared with the HG group, in the Cana groups, MAGI2 and nephrin expressions up-regulated (both P<0.01), the changes of cell morphology and cytoskeleton remodeling were alleviated. Meanwhile the Cana groups showed decreased SGLT2 expression ( P<0.05), lower ROS level, down- regulated NLRP3, ASC, cleaved-caspase1 expressions (all P<0.01), and decreased concentrations of IL-18 and IL-1β in culture medium of podocytes (both P<0.05). Conclusion:Cana can improve high glucose-induced injury and inflammation in human podocyte, possibly due to the repression of the ROS/NLRP3 signaling pathway.

(+)/(-)-Yanhusamides A-C, three pairs of unprecedented benzylisoquinoline-pyrrole hetero-dimeric alkaloid enantiomers from Corydalis yanhusuo

A chemical investigation on the aqueous extract of Corydalis yanhusuo tubers led to the isolation and structural elucidation of three pairs of trace enantiomeric hetero-dimeric alkaloids, (+)/(-)-yanhusamides A-C ( 1- 3), featuring an unprecedented 3,8-diazatricylco[5.2.2.02,6]undecane-8,10-diene bridged system. Their structures were exhaustively characterized by X-ray diffraction, comprehensive spectroscopic data analysis, and computational methods. Guided by the hypothetical biosynthetic pathway for 1- 3, a gram-scale biomimetic synthesis of (±)- 1 was achieved in 3 steps using photoenolization/Diels-Alder (PEDA) [4+2] cycloaddition. Compounds 1‒3 exhibited potent inhibition of NO production induced by LPS in RAW264.7 macrophages. The in vivo assay showed that oral administration of 30 mg/kg of (±)- 1 attenuated the severity of rat adjuvant-induced arthritis (AIA). Additionally, (±)- 1 induced a dose-dependent antinociceptive effect in the acetic acid-induced mice writhing assay.

Relationship between ANKK1 gene polymorphism and atypical antipsychotic drug-induced metabolic syndrome / 中国药房

OBJECTIVE To explore the relationship between the ANKK1 rs1800497 polymorphism and atypical antipsychotic drug-induced metabolic syndrome （MS）. METHODS Totally 94 patients with schizophrenia were included， and ANKK1 rs1800497 genotypes of patients were detected by micro-fluorescence immunoassay； social demographic information， clinical characteristics and other data were collected. The χ2 test was used to compare the correlation between the sex of patients and the occurrence of MS， and the correlation between gene polymorphism and the occurrence of MS and its risk factors.RESULTS Totally 94 patients included 24 cases （25.53%） of GG， 51 cases （54.26%） of GA and 19 cases of AA （20.21%）. Among them， there were 45 cases （47.87%） of MS， and the incidence of MS in male was higher than that in female （P＜0.05）. Genotype analysis showed that ANKK1 rs1800497 polymorphism was not associated with MS （P＝0.452）. ANKK1 rs1800497 A allele was significantly associated with hyperglycemia （χ2＝4.379， P＝0.036）， while it was not related to abdominal obesity， hypertension， high level of TG and low level of HDL-C （P＞0.05）， suggesting that for patients with schizophrenia， allele A was a relative risk factor for inducing hyperglycemia [OR＝2.008，95%CI（1.039， 3.881）]. CONCLUSIONS ANKK1 rs1800497 polymorphism has no correlation with the induction of MS by atypical antipsychotics， while the schizophrenia patients with A allele are more likely to induce hyperglycemia. The incidence of MS in male patients is significantly higher than that in female patients.

Research progress in 2023 ASCO-GU prostate cancer / 现代泌尿外科杂志

The 2023 American Society of Clinical Oncology Genitourinary Cancers Symposium unveiled numerous research advances which provide meaningful insights into the selection of treatment regimens of prostate cancer. Precision multi-treatment based on patients’ characteristics has become the predominant approach, including the use of a three-drug combination therapy for metastatic hormone-sensitive prostate cancer, and poly adenosine diphosphate ribose polymerase inhibitor therapy for metastatic castration-resistant prostate cancer. Nuclear medicine therapy and radiotherapy are also receiving significant attention. Integrated nuclear medicine diagnosis and therapy show immense potential for non-metastatic castration-resistant prostate cancer. Additionally, for localized prostate cancer, stereotactic body radiotherapy is a preferred alternative to surgery. This article sheds light on several key studies presented at the conference, focuses on prostate cancer treatment at different stages, and intends to enhance the therapeutic outcome for prostate cancer patients.

Monitoring results and influencing factors of clozapine plasma concentration in patients with mental disorders / 中国医师杂志

Objective:To analyze the influencing factors of clozapine plasma concentration in patients with mental disorders after oral administration, so as to provide reference for individualized treatment.Methods:Retrospective analysis was made on 221 inpatient reports of Clozapine blood concentration monitoring in the Therapeutic Drug Monitoring Laboratory (TDM) of the Pharmacy Department of the Chaohu Hospital Affiliated to Anhui Medical University from January to October 2021, and information such as patient gender, age, body mass index (BMI), smoking history, clozapine dose, combined drug use and blood concentration monitoring results were collected; Single factor analysis of variance and binary logistic regression were used to analyze the monitoring results of clozapine blood concentration in patients with mental disorders and its influencing factors.Results:Among 221 monitoring reports, 74 cases (normal concentration group) had clozapine plasma concentration within the effective plasma concentration range (350-600 ng/ml), 103 cases (low concentration group) were lower than the effective plasma concentration range (<350 ng/ml), and 44 cases (high concentration group) were higher than the effective plasma concentration range (>600 ng/ml). The results of single factor analysis of variance showed that there were statistically significant differences in daily dose of clozapine, standard dose, smoking history, course of disease, and abnormal liver function of patients in different blood concentration groups of clozapine (all P<0.05). The most frequently used antipsychotic drugs in 221 patients with clozapine were sodium valproate, amisulpride, aripiprazole and lithium carbonate in turn. The proportion of clozapine combined with ≥2 antipsychotics in the normal concentration group was higher than that in the low concentration group and the high concentration group, and the difference was statistically significant ( P<0.05). The results of binary logistic regression analysis showed that the combination of one antipsychotic drug and ≥ two antipsychotic drugs might help the blood concentration of clozapine in patients with mental disorders reach the target concentration (350-600 ng/ml), and the combination of two drugs was more beneficial [ OR(95% CI): 1.795(0.753-4.282)], with a statistically significant difference ( P<0.05). Conclusions:Clozapine plasma concentration varies greatly among individuals, and the therapeutic window is narrow. It is necessary to adjust the dosage in combination with the basic information and clinical information of patients, and regularly monitor the plasma concentration, so as to achieve the safety and effectiveness of individualized drug use.

Dermatomyositis with kidney neoplasm: two cases report and literature review / 中华泌尿外科杂志

Objective:To investigate the clinical characteristics, diagnosis and treatment of dermatomyositis with kidney neoplasm.Methods:The data of two patients with dermatomyositis complicated with kidney neoplasm in Tongji Hospital from January to February 2022 were retrospectively analyzed. The first case was a 55-year-old female, who was admitted with the chief complaints of recurrent erythema of upper extremities for 2 months and facial erythema for 1 month. Physical examination: erythema can be seen on upper limbs and face, no tenderness or percussion pain in kidney area. Myositis enzyme profile test showed that anti-Mi-2 antibody and anti-SSA /Ro-52 antibody were positive. Contrast CT showed nodular uneven enhancement in the right kidney with a size of 50 mm×41 mm. The second case was a 58-year-old female, who was admitted with the chief complaints of kidney occupying for a month. Physical examination: flaky erythema on face, no tenderness or percussion pain in kidney area. Myositis enzyme profile test showed that anti-Ro-52 antibody and anti-MDA5 antibody were positive. Contrast CT showed a significantly uneven enhanced mass with a size of about 50 mm×41 mm on left kidney. Both patients were diagnosed with kidney neoplasm before surgery and underwent laparoscopic partial nephrectomy in Tongji Hospital.Results:Both patients received regular oral prednisone after surgery. The pathological presentation of case 1 was papillary renal cell carcinoma, the facial erythema subsided 1 month after surgery, and there was no tumor recurrence for 13 months. The pathological presentation of case 2 was clear cell renal cell carcinoma, facial erythema subsided 2 weeks after surgery, and there was no tumor recurrence for 12 months.Conclusions:The diagnosis of dermatomyositis should be combined with clinical manifestations and laboratory examination, and the possibility of malignant tumor should be excluded due to the high likelihood of concomitant malignancy. For patients with dermatomyositis with kidney neoplasm, the main treatment is still surgery, and supplemented with glucocorticoid therapy.

Effect of two types of anesthesia on obturator nerve reflex and postoperative recovery in patients undergoing transurethral resection for bladder tumors / 基础医学与临床

Objective To observe the effects of ultrasound-guided modified obturator nerve block(ONB)combined with remazolam anesthesia on obturator nerve reflex(ONR)and postoperative recovery of patients with transurethral resection of bladder tumors(TURBT).Methods One hundred patients with bladder tumor admitted to Qinhuangd-ao Hospital from June 2019 to June 2021 were treated with TURBT.They were divided into conventional group(in-traspinal anesthesia+traditional ONB anesthesia)and ultrasound group(intraspinal anesthesia+improved ONB combined with remidazolam anesthesia under ultrasound guidance)with 50 cases in each according to different ONB methods.Perioperative indexes,hemodynamic indexes at different time points,intraoperative ONR occur-rence,complications and adverse anesthesia reactions were compared between the two groups.Results Compared with conventional group,ONB time,operation time,catheter indwelling time and hospital stay were shortened,and intraoperative blood loss was decreased in ultrasound group(P＜0.05).Compared with the conventional group at 30 min after administration(T1)and at the end of operation(T2),the mean arterial pressure(MAP)and oxygen saturation(SaO2)were increased in the ultrasound group(P＜0.05).Compared with the convention-al group,the incidence of ONR and bladder bleeding was decreased,and the incidence of postoperative bradycar-dia,nausea and vomiting were decreased in the ultrasound group(P＜0.05).Conclusions Ultrasound-guided modified ONB combined with remazolam anesthesia can effectively improve perioperative indexes of TURBT,re-duce intraoperative ONR and bladder bleeding,and have little influence on hemodynamics with few postoperative adverse anesthesia reactions.

IL-17 Imbalance Promotes thePyroptosis in Immune-Mediated L

Autoimmune hepatitis (AIH) affects all age group and occurs mainly in women. Pyroptosis is a novel programmed cell death featured with cell bursting and release of proinflammatory cytokines. A deeper understanding of AIH pathogenesis will contribute to novel therapy for AIH patients. Here, we aimed to investigate the role of IL-17 in immune-mediated liver injury.The levels of cytokines were measured by ELISA, and mRNA levels of STAT3 and IFN gammainducible protein 16 (IFI16) were detected by PCR. Expressions of STAT3, IFI16, gasdermin D and cleaved caspase-1 were measured by western-blotting. Immunohistochemical staining and transmission electron microscopy were applied to evaluate liver histopathological changes of the treated mice. Our results showed that the levels of IFI16 was increased in hepatocytes treated with IL-17 protein, and further elevated after STAT3-overexpressed (STAT3-OE) lentivirus treatment. The levels of IFI16 were reduced in hepatocytes treated with IL-17 neutralizing Ab (nAb), but were significantly increased after STAT3-OE treatment. Pyroptosis was observed in hepatocytes treated with IL-17 protein, and further cell damage was observed after STAT3-OE lentivirus treatment. Liver damage was alleviated in mice treated with IL-17 nAb, however sever damage was experienced after STAT3-OE lentivirus treatment. A binding interaction between IFI16 and STAT3 was detected in IL-17 treated hepatocytes. Glutathione transaminase activity was enhanced in concanavalin A-induced AIH mice compared to the control group (p<0.01). IL-17 plays an important role in activating STAT3 and up-regulating IFI16, which may promote the pyroptosis in AIH-related liver injury through STAT3-IFI16 axis.

Clinical characteristics and risk factors of COVID-19 patients with chronic hepatitis B: a multi-center retrospective cohort study / 医学前沿

The Coronavirus disease 2019 (COVID-19) has spread globally. Although mixed liver impairment has been reported in COVID-19 patients, the association of liver injury caused by specific subtype especially chronic hepatitis B (CHB) with COVID-19 has not been elucidated. In this multi-center, retrospective, and observational cohort study, 109 CHB and 327 non-CHB patients with COVID-19 were propensity score matched at an approximate ratio of 3:1 on the basis of age, sex, and comorbidities. Demographic characteristics, laboratory examinations, disease severity, and clinical outcomes were compared. Furthermore, univariable and multivariable logistic and Cox regression models were used to explore the risk factors for disease severity and mortality, respectively. A higher proportion of CHB patients (30 of 109 (27.52%)) developed into severe status than non-CHB patients (17 of 327 (5.20%)). In addition to previously reported liver impairment markers, such as alanine aminotransferase, aspartate aminotransferase, alkaline phosphatase, and total bilirubin, we identified several novel risk factors including elevated lactate dehydrogenase (⩾ 245 U/L, hazard ratio (HR) = 8.639, 95% confidence interval (CI) = 2.528-29.523; P < 0.001) and coagulation-related biomarker D-dimer (⩾ 0.5 µg/mL, HR = 4.321, 95% CI = 1.443-12.939; P = 0.009) and decreased albumin (< 35 g/L, HR = 0.131, 95% CI = 0.048-0.361; P < 0.001) and albumin/globulin ratio (< 1.5, HR = 0.123, 95% CI = 0.017-0.918; P = 0.041). In conclusion, COVID-19 patients with CHB were more likely to develop into severe illness and die. The risk factors that we identified may be helpful for early clinical surveillance of critical progression.

Objective:To investigate the expression level of circular RNA circ_0020123 in ovarian cancer (OC) , and then to evaluate the diagnostic value of circ_0020123 level in ovarian cancer.Methods:Fifty-five ovarian cancer patients who were diagnosed and treated in Hangzhou Linping District Maternal and Child Health Hospital from Oct. 2016 to Mar. 2017 were selected, and serum was collected for high-throughput gene expression sequencing analysis. The circ_0020123 level in serum of ovarian cancer patients and healthy controls was determined by real-time quantitative PCR, and the diagnostic efficacy of circ_0020123 level on ovarian cancer was evaluated by drawing receiver operating characteristic curve (ROC) . The correlation between the expression of circ_0020123 and the clinical characteristics of ovarian cancer patients was investigated by t-test. The survival curve was drawn to analyze the relationship between the serum circ_0020123 level and the prognosis and survival of ovarian cancer patients. Western blot was used to detect the expression levels of autophagy-related proteins LC3-II/LC3-I and p62.Results:Compared with the serum of healthy people (1±0.25) , the expression of circ_0020123 was significantly up-regulated in the serum of ovarian cancer patients (1.24±0.23) ( t=5.23, P<0.001) . The ROC curve showed that circ_0020123 had high diagnostic performance for the detection of ovarian cancer specimens (AUC=0.7579, P<0.001) . Comprehensive analysis of t test and logistic analysis showed that the high expression of circ_0020123 was significantly correlated with FIGO stage ( t=5.46, P<0.001) and tumor size ( t=6.37, P<0.001) . The measurement of survival data showed that the 5-year overall survival of the circ_0020123 high expression group was significantly shorter than that of the circ_0020123 low expression group ( P=0.019) . Knockdown of circ_0020123 in cells down-regulated the expression of autophagy-related proteins LC3-II/LC3-I (0.45±0.05) ( t=9.31, P=0.001) , and up-regulated the expression of p62 (1.94±0.11) ( t=12.62, P<0.001) . Conclusion:The results of this study indicate that circ_0020123 is an important ovarian cancer-related circular RNA, which provides a potential diagnostic, prognostic biomarker and therapeutic target for ovarian cancer patients.

With the rapid development of hospice care, more and more people pay attention to the quality of life of patients at the end of life. Due to the dialysis-related complications, heavy burden of comorbidities and cognitive impairment, elderly hemodialysis patients have poor quality of life, which brings heavy physiological, psychological and economic burdens to patients, families and society. Advance care planning can improve patients′ quality of life and save limited medical resources. By referring to relevant literature at home and abroad, this paper reviewed the overview of advance care planning, the necessity of discussing advance care planning with elderly hemodialysis patients, the implementation status and the obstacle factors. The purpose was to provide theoretical reference for better implementation of intervention treatment in elderly hemodialysis patients in China in the future.

Research progress on the regulation of cholesterol metabolism in the treatment of nonalcoholic fatty liver disease / 中华临床营养杂志

Nonalcoholic fatty liver disease (NAFLD) is one of the most common chronic liver diseases worldwide nowadays. Given the very complex pathogenesis, there are yet no effective pharmacological agents for the treatment of NAFLD. Accumulating evidence has shown that cholesterol metabolism dysregulation, resulting in excess cholesterol accumulation in the liver and subsequent hepatic inflammation and injury, is one of the most important causes for the occurrence and development of NAFLD. This suggests the application of cholesterol metabolism- targeting therapeutic strategy in NAFLD. This review firstly summarized the pathogenesis of NAFLD, then focused on the regulation of cholesterol metabolism and underlying mechanisms through which excess hepatic cholesterol contributed to NAFLD, and reviewed the research progress on cholesterol-lowering agents aimed at maintaining the cholesterol homeostasis to treat NAFLD, which would provide insights for novel strategies to treat NAFLD in both preclinical studies and clinical settings.

Effect of simple knee trainer on knee active flexion for hemiplegics after stroke / 中国康复理论与实践

@#Objective To observe the clinical efficacy of simple knee trainer on active knee flexion in patients with hemiplegia after stroke.Methods From March, 2020 to May, 2021, 46 hemiplegics after stroke in Beijing Bo'ai Hospital were randomly divided into control group (n = 23) and experimental group (n = 23). Both groups accepted routine rehabilitation training, and the experimental group accepted knee flexion exercise training in sitting position through the simple knee trainer, for eight weeks. They were measured active knee flexion angle in sitting position and maximum flexion angle in walking before and after training, as well as Holden Functional Ambulation Category (FAC).Results Both active knee flexion angle in sitting position and maximum flexion angle in walking significantly increased in both groups after training (|t| > 6.991, P < 0.001), and increased more in the experimental group than in the control group (t > 2.185, P < 0.05). The grade of FAC also improved in both groups (|Z| > 2.828, P < 0.01), and no significant difference was found between groups (Z = -0.821, P = 0.412).Conclusion The application of simple knee trainer can effectively improve the active range of motion of knee, which may be used in clinic- and community-based rehabilitation.

Effect of aquatic treadmill training on bilateral abdominal muscle thickness and balance function in stroke patients with hemiplegia / 中国康复理论与实践

ObjectiveTo explore the effect of aquatic treadmill training on abdominal muscle thickness and balance function in patients with hemiplegia after stroke. MethodsFrom March to October, 2021, 60 patients with hemiplegia after stroke were randomly divided into control group (n = 20), suspension group (n = 20) and aquatic treadmill group (n = 20). On the basis of comprehensive rehabilitation training, the control group received treadmill training, the suspension group received skyrail suspension walking training, and the aquatic treadmill group received treadmill training in water, for four weeks. The curative effect was evaluated by musculoskeletal ultrasound with muscle thickness of bilateral external oblique, internal oblique and transverse abdominal muscles. And they were assessed with Postural Assessment Scale for Stroke Patient (PASS) and Timed 'Up & Go' Test (TUGT) before and after treatment. ResultsAfter treatment, the thickness of external oblique and internal oblique muscles on the unaffected side, the PASS score and the TUGT time improved in all the three groups (|t| > 2.135, P < 0.05); while the thickness of external oblique, internal oblique and transverse abdominal muscles in the aquatic treadmill training group increased (|t| > 5.567, P < 0.001). The PASS score, the TUGT time, and the thickness of external oblique and internal oblique muscles on the affected side improved more in the aquatic treadmill training group than in the control group and the suspension group (P < 0.05). ConclusionThe aquatic treadmill training is more effective in strenghthening abdominal muscle to improve balance function.

Expression of NDV HN protein in rice and development of a semi-quantitative rapid method for detection of antibodies / 生物工程学报

The aim of this study was to develop a semi-quantitative immunochromatographic method for rapid detection of Newcastle disease virus (NDV) antibodies by expressing HN protein in rice endosperm bioreactor. The recombinant plasmid pUC57-HN was digested by MlyⅠ and XhoⅠ to retrieve the HN gene, while the intermediate vector pMP3 containing promoter, signal peptide and terminator was digested by NaeⅠ and XhoⅠ. The HN gene and the linearized pMP3 were purified and ligated to form a recombinant plasmid pMP3-HN1. Subsequently, pMP3-HN1 and plant vector pCAMBIA1300 were digested by EcoRⅠ and Hind Ⅲ, and the HN1 gene was cloned into pCAMBIA1300. The recombinant plasmid pCAMBIA1300-HN1 was introduced into Agrobacterium tumefaciens EHA105 by electrotransformation, and the pCAMBIA1300-HN1 was transferred into rice callus by agrobacterium-mediated method. After dark culture, callus screening, differentiation, rooting and transplanting, transgenic rice seeds were obtained 4 months later. PCR identified that the HN gene has been inserted into the rice genome. SDS-PAGE and Western blotting indicated that the HN protein was successfully expressed in the positive rice endosperm. The purity of the HN protein was more than 90% by SP cation exchange chromatography and gel filtration chromatography. According to the national standards for the diagnostic techniques of Newcastle disease HI test (HI≥4log2, positive antibody reaction), a colloidal gold labeled purified HN protein was used to prepare a semi-quantitative test strip by double-antibody sandwich method for rapid detection of NDV antibody. The results showed that the test strip did not cross-react with positive sera against other viruses, and the sensitivity of the test strip reached 1:102 400 for standard positive sera of Newcastle disease. Testing of a total of 308 clinical sera showed that the compliance rate of the test strip with HI test was 97.08%, and the Kappa value was 0.942. In conclusion, high purity recombinant HN protein was obtained from rice endosperm, and a simple, rapid, highly sensitive and highly specific semi-quantitative immunochromatographic strip was developed. The test strip could be used for immune evaluation of the Newcastle disease vaccine.

Identification and diagnosis of autism spectrum disorder among Chinese children in early stage / 中国学校卫生

Objective@#To investigate and explore the changes of the diagnosis of Chinese children with autism spectrum disorder (ASD).@*Methods@#The families of two groups of children aged 1-6 and 6-16 years who were diagnosed with ASD were selected from ALSOLIFE platform, and the online questionnaire was used to investigate the symptoms and its diagnosis related information. ANOVA was applied to compare the mean values, and χ 2 analysis was taken to compare the differences of two groups in the time of finding symptoms, the time of the first diagnosis, the time of treatment, and the diagnosis delayment.@*Results@#The initial recognition age of symptoms was 26.05 months age (2.17 years) in the young group (1-6 years), and 30.76 months age (2.56 years) in the old group (6-16 years). The age of first visit doctor was 28.21 months age (2.35 years) in the young group and 34.29 months (2.86 years) in the old group, while the average delay was only 3.43 months, of which the average delay was 4.52 months in the old group and 2.78 months in the young group. The age of diagnosed as ASD was 38.01 months age (3.17 years) in the young group and 31.07 months age (2.59 years) in the old group, while the average delay from first diagnosis to last diagnosis was 3.16 months. The delay from first diagnosis to last one was 3.71 months age in old age group, and 2.83 for the younger age group, The above differences were statistically significant ( F =328.30, 535.64, 507.71, 103.03, 17.79, P <0.01). Most of the children were still in the top hospitals to get diagnosed, but the role of child care was becoming more and more important.@*Conclusion@#The diagnosis efficiency of ASD children has been greatly improved, the time of symptom identification and diagnosis is advanced, and the delay of seeing a doctor and diagnosis is shortened.
