Methods The study design was one-year cluster randomized controlled trial of physical activity intervention （20 rain of daily exercise in the classroom） with an additional year of follow-up among 4 700 students aged 8-11 years at baseline. Results After the one-year intervention, BMI increased by 0.56 kg/m2 （SD 1.15） in the intervention group and by 0.72 kg/m^2 （SD 1.20） in the control group, with a mean difference of-0.15 kg/m^2 （95% CI： -0.28 to -0.02）. BMI z score decreased by -0.05 （SD 0.44） in the intervention group, but increased by 0.01 （SD 0.46） in the control group, with a mean difference of-0.07 （-0.13 to -0.01）. After another year of follow up, compared to the control group, children in the intervention group had significantly lower BMI （-0.13, -0.25 to -0.01 ）, BMI z score （-0.05, -0.10 to -0.01）, fat mass （-0.27 kg, -0.53 to -0.02） and percent body fat （-0.53, -1.00 to -0.05）. The intervention had a more pronounced effect on weight, height, BMI, BMI z score, and body composition among obese children than among normal weight or overweight children. Compared to the control group, the intervention group had a significantly higher percentage of children who maintained or reduced their BMI z score at year 1 （P-0.008） and year 2 （P=-0.04）. Conclusions These findings suggest that 20 min of daily moderate to vigorous physical activity during the school year is a feasible and effective way to prevent excessive gain of body weight, BMI, and body fatness in primary school students.展开更多

Methods A cross-sectional data of 41 087 adults （19 567 male and 21 520 female） from the 2002 China National Nutrition and Health Survey were examined. According to the obesity definition of WGOC （BMI, 24 kg/m^2 and 28 kg/m^2; WC, male 85 cm and 95 cm for male, 80 cm and 90 cm for female）, the study population were divided into 9 groups. The prevalence and odds ratio （ORs） of cardiovascular disease （CVD） risk factors （hypertension, high fasting plasma glucose and dyslipidemia） were compared among these 9 groups. Stepwise linear regression analyses were used to compare the likelihood of BMI and/or WC on CVD risk factors. Results Both the indexes levels and the odds ratios of CVD risk factors were significantly increased （decreased for HDL-C levels） along with the increase of WC and/or BMI, even when the effect of age, sex, income, education, sedentary activity and dietary factors were adjusted. The variances （R2） in CVD risk factors explained by WC only and BMI only were quite similar, but a little bit larger when WC and BMI were combined. The standard fl was higher of BMI when predicting systolic BP and was higher of WC when predicting TG, TC and HDL. Conclusions BMI and WC had independent effects on CVD risk factors and combination of BMI and WC would be more predictive. Findings from the present study provided substantive evidence for the WGOC recommendation of a combined use of BMI and WC classifications.展开更多

Methods PediaWic metabolic syndrome （MetS） and abnormality of each risk factor for MetS were defined using the criteria for US adolescents. Definition of hyper-TC, LDL, and dyslipidemia in adults was applied as well. The average level and abnormality rate of the metabolic indicators were described by BMI percentiles and compared with general linear model analysis. Receiver operating characteristic analysis was used to summarize the potential of BMI to discriminate between the presence and absence of the abnormality of these indicators. Results There was neither significantly increasing nor significantly decreasing trend of biochemical parameter levels in low BMI percentile range （〈65th）. Slight increasing trend from the 75th and a significant increase were found when BMI≥85th percentile. In general, the prevalence of the examined risk factors varied slightly when BMI percentile〈75th, and substantial increases were consistently seen when BMI percentile≥75th. As an indicator of hyper-TG, hypertension and MetS, the sensitivity and specificity were equal at the point of BMI〈75th percentile, and the Youden＇s index of risk factors also reached peak point before 75th percentile except for MetS. When the BMI percentile was used as the screening indicator of MetS, Youden＇s index reached peak point at 85th percentile, just the point in the ROC graph that was nearest to the upper left comer. Conclusion The BMI classification reference for overweight and obesity recommended by WGOC is rational to predict and prevent health risks in Chinese children and adolescents. Lower screening cut-off points, such as 83th percentile or 80th percentile, should not be excluded when they are considered as overweight criteria in future intervention or prevention studies.展开更多

Methods Association of WC with CV risk factors ...Objectives To explore the optimal threshold values of waist circumference （WC） for detecting cardiovascular （CV） risk factors among Chinese children and adolescents. Methods Association of WC with CV risk factors was studied among 65 898 children aged 7-18 years whose data were pooled from nine previous studies in China. CV risk factors in this study included hypertension （blood pressure above 95 percentile levels）, dyslipidemia （with one or more of the following three indexes： TG ≥ 1.7 mmol/L, TC ≥ 5.18 mmol/L, and HDL-C ≤ 1.04 mmol/L） and elevated glucose level （fasting plasma glucose ≥5.6 mmol/L）. Receive-operating characteristic analysis （ROC） and logistic regression were employed to derive optimal age- and sex-specific waist circumference references for predicting CV risk factors. Results A slight increasing trend of CV risk factors was observed starting from the 75th percentile of waist circumference in the study population, while a remarkable increasing trend occurred from the 90th percentile. The optimal waist circumference thresholds for predicting high blood pressures were at the 75th percentile for both boys and girls, which was at the 90th percentiles for detecting at least two of the above three CV risk factors. In comparison with children with waist circumference below the 75th percentile, the odds ratio of two CV risk factors doubled among children with waist circumference between the 75th and the 90th percentile, and increased by 6 times among children with waist circumference above the 90th percentile. The trend of high blood pressure increasing with waist circumference remained significant after having been stratified by BMI category. Conclusion The 75th and the 90th percentiles of WC are the optimal cut-off points for predicting an increased and a substantially increased risk of CV factors in Chinese children and adolescents, respectively.展开更多

Methods The fasting body weight and height of the third and fourth grade students （n=3886, aged 9 or 10 years） from 20 schools in Beijing, China, were measured, and the students were asked to choose the figures of body image and to complete the self-reported children＇s depression inventory （CDI） questionnaire. Results The CDI Cronbach＇s alpha was 0.81. The total CDI score was 9.60±7.50, 13.2% of children （boys 16.7% vs girls 9.5%） were at risk of developing depression symptoms. Overweight girls, but not boys, had significantly higher total CDI score than their normal weight counteparts. Both obese girls and boys showed a higher negative self-esteem score. More than one fifth underweight girls still wanted to be thinner while more than one third obese boys still wanted to be heavier. Children who wanted to be thinner showed slightly higher scores of ineffectiveness and negative self-esteem. After introducing the body dissatisfaction into the model, overweight was still associated with total CDI score among girls and obesity was still associated with negative self-esteem among both boys and girls. Conclusion Overweight girls show a significantly higher depression symptom score than their normal weight counterparts, which maybe partially explained by body dissatisfaction. Obese boys and girls are both more likely to suffer from low self-esteem, which is partially explained by body dissatisfaction.展开更多

The PBA-AuNPs hybrid system proposed here exhibits ordered photochemistry behaviors upon the addition of glucose at different pH values. There are two linear regions of glucose concentration for the glucose sensor at different pH values, i.e., between 0.1 mmol/L and 9.8 mmol/L at pH 6 with the detection limit of 64μmol/L and between 0 and 6.5 mmol/L with the detection limit of 48 μmol/L at pH 9, respectively. To test the practicality of the sensor system, we also applied this assay to detect a glucose sample in the artificial saliva.展开更多

The diagnosis ofhepatocellular carcinoma （HCC） in lobectomy specimens is usually straightforward, but distinguishing cirrhosis from well-differentiated HCC can be challenging in core biopsies. Our aims were to investigate the expression level of STAT3 and phosphorylated STAT3 （pSTAT3） in HCC and cirrhosis, and the application of STAT3 in the differential diagnosis of HCC and cirrhosis. Methods： Sixty cases were divided into three groups： patients with HCC only （Group 1）, HCC and cirrhosis （Group 2）, and cirrhosis only （Group 3）. Formalin-fixed and paraffin-embedded tissue sections were stained immunohistochemically for STAT3, pSTAT3, and CD163. The values obtained from the tissue sections of each group were compared in statistical analysis. Results： STAT3 showed a high level in HCC and was a significant marker for differentiating HCC from cirrhosis （P 〈 0.0001 ）. The odds ratio between HCC and cirrhosis increased 34.4 times when the intensity of STAT3 increased by 1 level. Spearman＇s correlation and Chi-square tests also demonstrated that expression level of STAT3 did not correlate with age, gender, or the presence of a cirrhotic background. Conclusions： STAT3 staining differs significantly in HCC and cirrhosis. The findings reinforce the role of STAT3 in the tumorigenesis of HCC and provide a useful marker to differentiate HCC from cirrhosis in challenging liver biopsies.展开更多

文摘Functional dyspepsia(FD),characterized by persistent or recurrent dyspeptic symptoms without identifiable organic,systemic or metabolic causes,is an increasingly recognized global health issue.The objective of this guideline is to equip clinicians and nursing professionals with evidence-based strategies for the management and treatment of adult patients with FD using traditional Chinese medicine(TCM).The Guideline Development Group consulted existing TCM consensus documents on FD and convened a panel of 35 clinicians to generate initial clinical queries.To address these queries,a systematic literature search was conducted across PubMed,EMBASE,the Cochrane Library,China National Knowledge Infrastructure(CNKI),VIP Database,China Biology Medicine(SinoMed)Database,Wanfang Database,Traditional Medicine Research Data Expanded(TMRDE),and the Traditional Chinese Medical Literature Analysis and Retrieval System(TCMLARS).The evidence from the literature was critically appraised using the Grading of Recommendations Assessment,Development,and Evaluation(GRADE)approach.The strength of the recommendations was ascertained through a consensus-building process involving TCM and allopathic medicine experts,methodologists,pharmacologists,nursing specialists,and health economists,leveraging their collective expertise and empirical knowledge.The guideline comprises a total of 43 evidence-informed recommendations that span a range of clinical aspects,including the pathogenesis according to TCM,diagnostic approaches,therapeutic interventions,efficacy assessments,and prognostic considerations.
文摘BACKGROUND Breast non-mass-like lesions(NMLs)account for 9.2%of all breast lesions.The specificity of the ultrasound diagnosis of NMLs is low,and it cannot be objectively classified according to the 5th Edition of the Breast Imaging Reporting and Data System(BI-RADS).Contrast-enhanced ultrasound(CEUS)can help to differentiate and classify breast lesions but there are few studies on NMLs alone.AIM To analyze the features of benign and malignant breast NMLs in grayscale ultrasonography(US),color Doppler flow imaging(CDFI)and CEUS,and to explore the efficacy of the combined diagnosis of NMLs and the effect of CEUS on the BI-RADS classification of NMLs.METHODS A total of 51 breast NMLs verified by pathology were analyzed in our hospital from January 2017 to April 2019.All lesions were examined by US,CDFI and CEUS,and their features from those examinations were analyzed.With pathology as the gold standard,binary logic regression was used to analyze the independent risk factors for malignant breast NMLs,and a regression equation was established to calculate the efficiency of combined diagnosis.Based on the regression equation,the combined diagnostic efficiency of US combined with CEUS(US+CEUS)was determined.The initial BI-RADS-US classification of NMLs was adjusted according to the independent risk factors identified by CEUS,and the diagnostic efficiency of CEUS combined with BI-RADS(CEUS+BI-RADS)was calculated based on the results.ROC curves were drawn to compare the diagnostic values of the three methods,including US,US+CEUS,and CEUS+BI-RADS,for benign and malignant NMLs.RESULTS Microcalcification,enhancement time,enhancement intensity,lesion scope,and peripheral blood vessels were significantly different between benign and malignant NMLs.Among these features,microcalcification,higher enhancement,and lesion scope were identified as independent risk factors for malignant breast NMLs.When US,US+CEUS,and CEUS+BI-RADS were used to identify the benign and malignant breast NMLs,their sensitivity rates were 82.6%,91.3%,and 87.0%,respectively;their specificity rates were 71.4%,89.2%,and 92.9%,respectively;their positive predictive values were 70.4%,87.5%,and 90.9%,respectively;their negative predictive values were 83.3%,92.6%,and 89.7%,respectively;their accuracy rates were 76.5%,90.2%,and 90.2%,respectively;and their corresponding areas under ROC curves were 0.752,0.877 and 0.903,respectively.Z tests showed that the area under the ROC curve of US was statistically smaller than that of US+CEUS and CEUS+BI-RADS,and there was no statistical difference between US+CEUS and CEUS+BI-RADS.CONCLUSION US combined with CEUS can improve diagnostic efficiency for NMLs.The adjustment of the BI-RADS classification according to the features of contrastenhanced US of NMLs enables the diagnostic results to be simple and intuitive,facilitates the management of NMLs,and effectively reduces the incidence of unnecessary biopsy.

文摘Objectives To determine whether a large-scale physical activity intervention could affect body composition in primary school students in Beijing, China. Methods The study design was one-year cluster randomized controlled trial of physical activity intervention （20 rain of daily exercise in the classroom） with an additional year of follow-up among 4 700 students aged 8-11 years at baseline. Results After the one-year intervention, BMI increased by 0.56 kg/m2 （SD 1.15） in the intervention group and by 0.72 kg/m^2 （SD 1.20） in the control group, with a mean difference of-0.15 kg/m^2 （95% CI： -0.28 to -0.02）. BMI z score decreased by -0.05 （SD 0.44） in the intervention group, but increased by 0.01 （SD 0.46） in the control group, with a mean difference of-0.07 （-0.13 to -0.01）. After another year of follow up, compared to the control group, children in the intervention group had significantly lower BMI （-0.13, -0.25 to -0.01 ）, BMI z score （-0.05, -0.10 to -0.01）, fat mass （-0.27 kg, -0.53 to -0.02） and percent body fat （-0.53, -1.00 to -0.05）. The intervention had a more pronounced effect on weight, height, BMI, BMI z score, and body composition among obese children than among normal weight or overweight children. Compared to the control group, the intervention group had a significantly higher percentage of children who maintained or reduced their BMI z score at year 1 （P-0.008） and year 2 （P=-0.04）. Conclusions These findings suggest that 20 min of daily moderate to vigorous physical activity during the school year is a feasible and effective way to prevent excessive gain of body weight, BMI, and body fatness in primary school students.
文摘Objective:To develop a self-management behaviour tool for liver cirrhosis patients in China.Methods:A provisional scale comprising 30 items was developed based on the results of literature review,semi-structured interviews,expert consultation and pilot study.Patients with hepatic cirrhosis(n=180)from four grade A tertiary hospitals in Tianjin and Handan Infectious Disease Hospital were assessed using the provisional self-management scale comprising 30 items in four dimensions.The reliability and validity of the scale were tested and a final version of the self-management scale for liver cirrhosis comprising 24 items was concluded.Results:The overall Cronbach's a for the scale was 0.80,ranging from 0.60 to 0.69 in each dimension.The testeretest correlation was 0.84,ranging from 0.54 to 0.72 in each dimension.Content validity for the scale was 0.93.Nine factors were extracted by a factor analysis method,which were limited to four factors according to a scree test.The cumulative variance contribution rate was 56.98%.Conclusion:This scale has good reliability and validity and can be used to evaluate selfmanagement behaviour of hepatic cirrhosis patients and provides a reference for behaviour intervention.
文摘Background Growth-differentiation factor-15(GDF-15)is a promising prognostic biomarker in patients with chronic heart failure (CHF).Comparatively little is known about the value of repeated measurement of GDF-15with CI-IF in Chinese Han population.This study sought to identify the clinical value of repeated measurement of GDF-15in Chinese Han patients with post-myocardial infarction CHF. Methods In total,232consecutive Chinese Hart patients with post-myocardial infarction CHF were enrolled prospectively from January 2014to June 2016.The plasma concentration of GDF-15was determined on admission and over 12months.Patients were followed up for all-cause death and a composite outcome of major adverse cardiac events (MACE)included all-cause death,myocardial infarction and first heart failure (HF)re-hospitalization.Association with other clinical variables and adverse outcomes of repeated measurement of GDF-15 was explored.Results The median baseline GDF-15level was 2025ng/L.Baseline GDF-15was moderately associated with baseline N-terminal pro-B type nalriuretic peptide (NT-proBNP)(coefficient 0.561,P <0.001).During a median follow-up of 20months,there were 53deaths and 100MACE.GDF-I5remained an independent predictor of all-cause death (adjusted hazard ratio 1.826per 1Ln U,95%CI: 1.037-8.360;P =0.037)and MACE (adjusted hazard ratio 2.243per I Ln U,95%CI:1.181-1.775;P <0.001)adjusted for established risk factors.Repeated measurement of GDF-15was performed in 173survivals over 12months.Increase of GDF-15over 12months was associ- ated with dilatation of left ventricle and acted as an independent predictor of subsequent all-canse death (adjusted HR =3.164,95%CI: 1.245~.041;P =0.015).In the joint model,GDF-15was also shown to be a risk factor for all-cause death (HR =2.749,95%CI: 1.667-3.831;P <0.001)and MACE (FIR =2.434,95%CI:1.425-3.443;P <0.001).Conclusions Repeated measurements of GDF-15 have promising prognostic value of the risk of all-cause death in Chinese Han patients with CI-IF post-myocardial infarction.GDF-15may influence the post-myocardial infarction CI-IF through the path physiological pathway of myocardial remodeling.

文摘Objective To compare the relative risk of waist circumference （WC） and/or BMI on cardiovascular risk factors. Methods A cross-sectional data of 41 087 adults （19 567 male and 21 520 female） from the 2002 China National Nutrition and Health Survey were examined. According to the obesity definition of WGOC （BMI, 24 kg/m^2 and 28 kg/m^2; WC, male 85 cm and 95 cm for male, 80 cm and 90 cm for female）, the study population were divided into 9 groups. The prevalence and odds ratio （ORs） of cardiovascular disease （CVD） risk factors （hypertension, high fasting plasma glucose and dyslipidemia） were compared among these 9 groups. Stepwise linear regression analyses were used to compare the likelihood of BMI and/or WC on CVD risk factors. Results Both the indexes levels and the odds ratios of CVD risk factors were significantly increased （decreased for HDL-C levels） along with the increase of WC and/or BMI, even when the effect of age, sex, income, education, sedentary activity and dietary factors were adjusted. The variances （R2） in CVD risk factors explained by WC only and BMI only were quite similar, but a little bit larger when WC and BMI were combined. The standard fl was higher of BMI when predicting systolic BP and was higher of WC when predicting TG, TC and HDL. Conclusions BMI and WC had independent effects on CVD risk factors and combination of BMI and WC would be more predictive. Findings from the present study provided substantive evidence for the WGOC recommendation of a combined use of BMI and WC classifications.

文摘Objective To verify Working Group for Obesity in China （WGOC） recommended body mass index （BMI） classification reference for overweight and obesity in Chinese children and adolescents using the data of 2002 China Nationwide Nutrition and Health Survey. Methods PediaWic metabolic syndrome （MetS） and abnormality of each risk factor for MetS were defined using the criteria for US adolescents. Definition of hyper-TC, LDL, and dyslipidemia in adults was applied as well. The average level and abnormality rate of the metabolic indicators were described by BMI percentiles and compared with general linear model analysis. Receiver operating characteristic analysis was used to summarize the potential of BMI to discriminate between the presence and absence of the abnormality of these indicators. Results There was neither significantly increasing nor significantly decreasing trend of biochemical parameter levels in low BMI percentile range （〈65th）. Slight increasing trend from the 75th and a significant increase were found when BMI≥85th percentile. In general, the prevalence of the examined risk factors varied slightly when BMI percentile〈75th, and substantial increases were consistently seen when BMI percentile≥75th. As an indicator of hyper-TG, hypertension and MetS, the sensitivity and specificity were equal at the point of BMI〈75th percentile, and the Youden＇s index of risk factors also reached peak point before 75th percentile except for MetS. When the BMI percentile was used as the screening indicator of MetS, Youden＇s index reached peak point at 85th percentile, just the point in the ROC graph that was nearest to the upper left comer. Conclusion The BMI classification reference for overweight and obesity recommended by WGOC is rational to predict and prevent health risks in Chinese children and adolescents. Lower screening cut-off points, such as 83th percentile or 80th percentile, should not be excluded when they are considered as overweight criteria in future intervention or prevention studies.

文摘Objectives To explore the optimal threshold values of waist circumference （WC） for detecting cardiovascular （CV） risk factors among Chinese children and adolescents. Methods Association of WC with CV risk factors was studied among 65 898 children aged 7-18 years whose data were pooled from nine previous studies in China. CV risk factors in this study included hypertension （blood pressure above 95 percentile levels）, dyslipidemia （with one or more of the following three indexes： TG ≥ 1.7 mmol/L, TC ≥ 5.18 mmol/L, and HDL-C ≤ 1.04 mmol/L） and elevated glucose level （fasting plasma glucose ≥5.6 mmol/L）. Receive-operating characteristic analysis （ROC） and logistic regression were employed to derive optimal age- and sex-specific waist circumference references for predicting CV risk factors. Results A slight increasing trend of CV risk factors was observed starting from the 75th percentile of waist circumference in the study population, while a remarkable increasing trend occurred from the 90th percentile. The optimal waist circumference thresholds for predicting high blood pressures were at the 75th percentile for both boys and girls, which was at the 90th percentiles for detecting at least two of the above three CV risk factors. In comparison with children with waist circumference below the 75th percentile, the odds ratio of two CV risk factors doubled among children with waist circumference between the 75th and the 90th percentile, and increased by 6 times among children with waist circumference above the 90th percentile. The trend of high blood pressure increasing with waist circumference remained significant after having been stratified by BMI category. Conclusion The 75th and the 90th percentiles of WC are the optimal cut-off points for predicting an increased and a substantially increased risk of CV factors in Chinese children and adolescents, respectively.

文摘Objective To investigate the relationship between body weight, body dissatisfaction and depression symptoms among Chinese children. Methods The fasting body weight and height of the third and fourth grade students （n=3886, aged 9 or 10 years） from 20 schools in Beijing, China, were measured, and the students were asked to choose the figures of body image and to complete the self-reported children＇s depression inventory （CDI） questionnaire. Results The CDI Cronbach＇s alpha was 0.81. The total CDI score was 9.60±7.50, 13.2% of children （boys 16.7% vs girls 9.5%） were at risk of developing depression symptoms. Overweight girls, but not boys, had significantly higher total CDI score than their normal weight counteparts. Both obese girls and boys showed a higher negative self-esteem score. More than one fifth underweight girls still wanted to be thinner while more than one third obese boys still wanted to be heavier. Children who wanted to be thinner showed slightly higher scores of ineffectiveness and negative self-esteem. After introducing the body dissatisfaction into the model, overweight was still associated with total CDI score among girls and obesity was still associated with negative self-esteem among both boys and girls. Conclusion Overweight girls show a significantly higher depression symptom score than their normal weight counterparts, which maybe partially explained by body dissatisfaction. Obese boys and girls are both more likely to suffer from low self-esteem, which is partially explained by body dissatisfaction.

文摘BACKGROUND Spasmolytic polypeptide-expressing metaplasia(SPEM)is a potential preneoplastic lesion.AIM To elucidate the microRNA(miR)-7-mediated preventive and inhibitive effects of Yiwei Xiaoyu granules(YWXY)in SPEM lesions.METHODS Gastric mucosa biopsies were collected from chronic atrophic gastritis patients and healthy people with signed informed consent.YWXY was administered to the mice with induced SPEM by tamoxifen,and the gastric mucosa was harvested on the tenth day of the experiment.Then immunohistochemistry and immunofluorescence were performed to validate the SPEM,lesions and the potential mechanism was investigated.RNA transcripts were detected with reverse transcriptionquantitative polymerase chain reaction.RESULTS The expression of miR-7 was downregulated in the SPEM lesions,and expression of trefoil factor 2(TFF2)and clusterin was high in the human gastric mucosa.In vivo experiments showed that YWXY could inhibit the cell proliferation in the tamoxifen-induced SPEM lesions by regulating Ki67.Simultaneously,YWXY could restore the expression of miR-7 by regulating TFF2 by detection with immunofluorescence but not with reverse transcription-quantitative polymerase chain reaction,indicating its potential mechanism of targeting miR-7 by mediating TFF2.The expression of vascular endothelial growth factor-βand gastric intrinsic factor was restored within 3 d of YWXY administration for the SPEM lesions,speculating that the possible mechanism of YWXY is to inhibit the development and progression of SPEM by regulating vascular endothelial growth factor-βand gastric intrinsic factor.CONCLUSION miR-7 downregulation is an early event in SPEM through regulation of TFF2 in human gastric mucosa.YWXY is able to inhibit the cell proliferation and restore the expression of miR-7 by mediating TFF2 in the SPEM mouse model.

文摘A simple, cheap and non-enzymatic colorimetric strategy for glucose detection has been designed based on the interactions between a phenylboronic acid （PBA） derivative, which is coupled with gold nanoparticles （AuNPs） as the colorimetric reporters, and glucose. The PBA-AuNPs hybrid system proposed here exhibits ordered photochemistry behaviors upon the addition of glucose at different pH values. There are two linear regions of glucose concentration for the glucose sensor at different pH values, i.e., between 0.1 mmol/L and 9.8 mmol/L at pH 6 with the detection limit of 64μmol/L and between 0 and 6.5 mmol/L with the detection limit of 48 μmol/L at pH 9, respectively. To test the practicality of the sensor system, we also applied this assay to detect a glucose sample in the artificial saliva.

文摘BACKGROUND The Correa sequence,initiated by Helicobacter pylori(H.pylori),commonly progresses to gastric cancer through the stage of chronic atrophic gastritis(CAG).Although eradication of H.pylori only reduces the risk of gastric cancer,it does not eliminate the risk for neoplastic progression.Yiwei Xiaoyu granules(YWXY)are a commonly used composite preparation in Chinese clinics.However,the pursuit of excellence in clinical trials and the establishment of standardized animal experiments are still needed to contribute to full understanding and application of traditional Chinese medicine in the treatment of CAG.AIM To demonstrate the effectiveness of YWXY in patients with CAG and spleenstomach deficiency syndrome(DSSS),by alleviating histological scores,improving response rates for pathological lesions,and achieving clinical efficacy in relieving DSSS symptoms.METHODS We designed a double-blind,randomized,controlled trial.The study enrolled seventy-two H.pylori-negative patients(mean age,52.3 years;38 men)who were randomly allocated to either the treatment group or control group in a 1:1 ratio,and treated with 15 g YWXY or 0.36 g Weifuchun(WFC)tablet combined with the respective dummy for 24 wk.The pre-randomization phase resulted in the exclusion of 72 patients:50 participants did not meet the inclusion criteria,12 participants declined to participate,and 10 participants were excluded for various other reasons.Seven visits were conducted during the study,and histopathological examination with target endoscopic biopsy of narrow-band imaging was requested before the first and seventh visits.We also evaluated endoscopic performance scores,total symptom scores,serum pepsinogen and gastrin-17.RESULTS Six patients did not complete the trial procedures.Treatment with YWXY improved the Operative Link on Gastric Intestinal Metaplasia Assessment(OLGIM)stage,compared with WFC(P<0.05).YWXY provided better relief from symptoms of DSSS and better improvement in serum gastric function,compared with WFC(P<0.05).CONCLUSION YWXY compared with WFC significantly reduced the risk of mild or moderate atrophic disease,according to OLGIM stage,significantly relieved symptoms of DSSS,and improved serum gastric function.

文摘Background：The efficacy of percutaneous intradiscal radiofrequency thermocoagulation （PIRFT） for the treatment of discogenic low back pain （LBP） remains controversial.However,all the PIRFT studies utilized monopolar radiofrequency thermocoagulation （RFTC）.The aim of this study was to investigate the safety and efficacy of bipolar RFTC for the treatment of discogenic LBP.Methods：A total of 23 patients with discogenic LBP were treated with single-level bipolar RFTC.The patients were assessed before the procedure and at 1 week,1 month,3 months,6 months,and 1 year after the procedure.The primary outcome included the visual analog scale （VAS） score and the Oswestry Disability Index （ODI） score.The secondary outcome included pain relief,reduction of analgesic dose,and patient satisfaction.Results：The VAS and ODI scores were significantly decreased after bipolar RFTC treatment at all time points of follow-up （P 〈 0.05）.Bipolar RFTC treatment also resulted in a significant change in all secondary measures,such as pain relief,reduction of analgesic dose,and patient satisfaction.No serious complications or neurological sequelae were observed in any of the patients.Conclusions：Bipolar RFTC treatment can significantly attenuate pain and improve the function of patients with discogenic LBP.
文摘Background： Overexpression and constitutive activation of signal transducer and activator of transcription （STAT） 3 have been suggested in the tumorigenesis of many human cancers, including multiple carcinomas, melanoma, and lymphoma. The diagnosis ofhepatocellular carcinoma （HCC） in lobectomy specimens is usually straightforward, but distinguishing cirrhosis from well-differentiated HCC can be challenging in core biopsies. Our aims were to investigate the expression level of STAT3 and phosphorylated STAT3 （pSTAT3） in HCC and cirrhosis, and the application of STAT3 in the differential diagnosis of HCC and cirrhosis. Methods： Sixty cases were divided into three groups： patients with HCC only （Group 1）, HCC and cirrhosis （Group 2）, and cirrhosis only （Group 3）. Formalin-fixed and paraffin-embedded tissue sections were stained immunohistochemically for STAT3, pSTAT3, and CD163. The values obtained from the tissue sections of each group were compared in statistical analysis. Results： STAT3 showed a high level in HCC and was a significant marker for differentiating HCC from cirrhosis （P 〈 0.0001 ）. The odds ratio between HCC and cirrhosis increased 34.4 times when the intensity of STAT3 increased by 1 level. Spearman＇s correlation and Chi-square tests also demonstrated that expression level of STAT3 did not correlate with age, gender, or the presence of a cirrhotic background. Conclusions： STAT3 staining differs significantly in HCC and cirrhosis. The findings reinforce the role of STAT3 in the tumorigenesis of HCC and provide a useful marker to differentiate HCC from cirrhosis in challenging liver biopsies.
