Objective To investigate whether there is a correlation between the esophageal length of the adult Chinese people and their height, sitting height, sex or age. Methods The length from the upper end of esophagus to the dentate line of the cardia was measured by watching esophageal cavity with endoscope. A total of 613 cases (378 males and 235 females) were studied. Results ① The average length of esophagus was (24.8?2.1)cm for male and (22.8?1.9)cm for female. The difference between male and female was statistically significant (P

Due to a great amount of data in clinical trials, the data cleansing needs to adopt a variety of measures, including the latest developed visual check approach. According to the different types of clinical data and the different stages in the course of clinical data management, this study reviews 8 types of visual graphics that show the relevance and trend among the data. The series of graphics can rapidly detect abnormal data, monitor clinical research in real-time, make the data management process much easier and improve the clinical trial efficiency and data quality.

Electronic case report forms (eCRFs) instead of the traditional paper case report forms (pCRFs) are increasingly used by investigators and sponsors of clinical research. We include a total of 14 phase III studies (8 pCRF, 6 eCRF) to compare paper and electronic data documentation both quantitatively and qualitatively in clinical studies. The result suggests that adaptions of electronic data capture (EDC) in clinical trials have the advantages in optimization of data capture process, improvement of data quality and earlier clinical decision compared to paper-based methods. Furthermore, the successful implementation of EDC requires accouplements with corresponding data management processes and reallocation of resources.

Objective To explore the clinical effect and prognosis of plasma N -terminal probrain natriuret-ic peptide (NT -proBNP)and 6 min walk test performance (6 -MWT)in patients with chronic heart failure (CHF).Methods 100 patients with CHF were selected as observation group,and 50 healthy people were selected as control group.They were grouped by NYHA degree,28 cases were NYHA Ⅱ,56 cases were NYHA Ⅲ and 16 cases were NYHA Ⅳ.The plasma level of NT -proBNP,6 -MWT,left ventricular ejection fraction (LVEF),early diastolic peak mitral flow velocity to late diastolic peak mitral flow velocity (E /A)were measured.Results The plasma NT -proBNP level of CHF patients was positively correlated with NYHA degree (r =0.683,P <0.01);6 -MWT was neg-atively correlated with NYHA degree(r =-0.518,P <0.01).For CHF patients,significant correlation was observed between NT -proBNP and 6 -MWT (r =-0.789,P <0.05).Plasma NT -proBNP level was correlated with dias-tolic HF,systolic HF and mixed type heart failure (r =-0.678,P <0.01;r =-0.845,P <0.01;r =-0.759,P <0.01).Conclusion Plasma NT -proBNP,6 -MWT can serve as a marker for the detection and evaluation of heart failure.Meanwhile,the higher the NT -proBNP level,the shorter the 6 -MWT,the more serious the heart failure,the poorer the prognosis.

Objective To observe the therapeutic effect of electroacupuncture (EA) on acupoints located along anterior and posterior thigh muscles plus isokinetic muscle strength training for poststroke lower limb dysfunction. Methods Fifty-two qualified mild hemiplegia cases were randomized into control group A ( N=17) , control group B (N=17), and observation group (N=18 ). Control group A was given conventional rehabilitation training, control group B was given conventional rehabilitation training and task-targeting knee strength-coordination isokinetic muscle strength training based on visual feedback, and observation group was given EA on acupoints located along anterior and posterior thigh muscles plus the treatment for control group B. The treatment for the three groups was performed once a day, five days a week, lasting 3 weeks. Before and after treatment, the lower limb motor function, peak torque ( PT) of knee flexion and extension muscles, and gait speed and gait symmetry were monitored. Results After treatment for 3 weeks, the lower limb motor function, PT and gait symmetry were much improved in the three groups (P<0.05 compared with those before treatment) . Except that the gait speed and lower limb muscle tension of observation group did not differ from those of control group B ( P>0.05) , the improvement of observation indexes of control group B was superior to that of control group A, and the improvement of observation indexes of observation group was more obvious than that of the two control groups ( P<0.05) . Conclusion EA on acupoints located along anterior and posterior thigh muscles plus isokinetic muscle strength training is more effective for improving lower limb motor function of poststroke lower limb dysfunction patients than conventional isokinetic training.

Objective To evaluate the serum 25-hydroxyvitamin D [25 (OH)D3] levels in non-diabetic people in Taiyuan community,and its relationship with obesity and abdominal obesity.Methods This crosssectional study enrolled 417 non-diabetic people in Tainyuan community from July to September in 2011 [225 males and 192 females,mean age (47.6 ±7.8) years].For all the enrolled subjects,we collected data about anthropometric indexes,medical history,blood glucose,lipid profile,25 (OH) D3,fasting insulin (Fins) level,homeostasis model assessement for insulin resistance (HOMA-IR),body fat content (％) measured with dualenergy X-ray absorptiometry (DEXA),and intra-abdominal adipose tissue (IAAT) and abdominal subcutaneous adipose tissue (SCAT) calculated based on magnetic resonance imaging at the 4th to 5th lumbar disc level (IAAT≥80 cm2 was considered abdominal obesity).Correlation analysis was performed to assess the relationships of serum 25 (OH) D3 levels with biochemical and body fat indexes.Results The average serum level of 25 (OH) D3 was 44.5 nmol/L in the 417 people,with vitamin D deficiency in 261 cases (62.6％) and vitamin D insufficiency in 109 cases (26.1％).Of the vitamin D deficient and insufficient people,77.6％ had abdominal obesity according to IAAT (IAAT ≥ 80 cm2).According to Pearson analysis result,lg 25 (OH)D3 was negatively correlated with lg Fins,lg HOMA-IR,waist circumference,systolic blood pressure,diastolic blood pressure,total abdominal adipose tissue (TAAT),IAAT (all P ＜0.05).It was also negatively correlated with waist-to-hip-ratio,body mass index (BMI),and body fat content (％),but without statistical significance (all P ＞0.05).In stepwise multiple linear regression model,lg HOMA-IR (t =-4.278,P =0.001) and TAAT (t =-5.146,P =0.002) were independently correlated with lg 25 (OH) D3.Conclusions About 90％ of all non-diabetic population in Taiyuan community have vitamin D deficiency or insufficiency,of whom 4/5 have abdominal obesity.Serum 25 (OH)D3 level is negatively correlated with abdominal adipose tissue,but not significantly associated with BMI.HOMA-IR and TAAT are independent risk factors for vitamin D deficiency.
