Objective To explore the method to relieve fingertip pain in monitoring fingertip blood glucose.Methods A total of 130 newly admitted patients with type 2 diabetes received glucose monitoring 6 times daily at different time points.Blood sampling was taken from different sites including the central and top of middle finger pulp,central and side of ring finger pulp,top of middle finger with pressing the acupoint of Hegu at the same time or pressing acupoint of Hegu for 1 minute before blood taking.Pain degree was assessed by numeric rating scale after blood glucose taking.Pain scores were compared among the different methods.Results There were significant differences in pain scores between different methods (x2 =164.83,P＜0.05).Pain score was higher in sampling blood on the side of ring finger pulp,while the proportion of subjects with mild pain after pressing Hegu was increased significantly.There were significant differences in pain scores between subjects with versus without pressing Hegu (all P＜0.05).Pain degree was reduced more significantly by pressing Hegu for 1 minute before blood taking than pressing Hegu at the same time of sampling blood,and the former had a higher proportion of subjects with only mild pain than the latter (x2 =10.44,P＜0.01).There were no significant differences in pain scores between the other methods (all P＞ 0.05).Conclusions Pressing Hegu can effectively reduce fingertip pain in fingertip blood glucose monitoring,and pressing Hegu for 1 minute before blood taking is more effective.

Objective To evaluate the effect of situational health education in glycemic control in type 2 diabetes patients.Methods A total of 98 patients with type 2 diabetes was randomly assigned to the control(n=49)and the study group(n=49).The control group received conventional diabetes education,while the study group received situational health education.Fasting blood glucose(FBG),2-hour plasma glucose (2 hPG),HbAlc and the self-care behaviors were observed at baseline and 1-year after the intervention.Paired t test was used for data analysis.Results FPG,2hPG,HbA1c and self-care behavior scores were not significantly different between the two group at baseline.After 1-year intervention,FPG,2hPG and HbA1c of the two groups were significantly decreased,and FPG,2hPG and HbA1c of the study group were significantly lower than those of the control group(t values were 2.71,3.35 and 2.90,respectively; all P＜ 0.05).In comparison with the control group,self-care scores of the study group were increased(t values were 7.36,6.51,5.24,5.07,6.57 and 6.77,respectively; all P＜0.05).Conclusion Situational health education could improve self-management and glycemic control of type 2 diabetic patients.

Objective To investigate the relationship of parity and other reproduction-associated factors with metabolic syndrome(MS) in middle-aged and elderly women in Nanchang community.Methods Female permanent residents over 40 years old were sampled for a routine examination and a questionnaire survey covering basic information,5 894 subjects were enrolled and identified as effective cases.MS was diagnosed according to the standard of China Diabetes Society in 2004.Factors including age,education,profession,marital status,parity,child-bearing history of macrosomia,breastfeeding,menarche age,and menopausal age were analyzed in order to find their relationship with MS.The univariate logistic analysis was followed by binary logistic regression analysis if P＜0.05,and OR value and confidence interval were calculated.Results Univariate logistic regression analysis showed that age,education,profession,parity,breastfeeding,and menopausal age were influencing factors of MS (all P ＜ 0.05).There was no correlation to marital status,miscarriage history,child-bearing history of macrosomia,menarche age with MS(all P＞0.05).Binary Logistic regression analysis showed that the risk of MS increased with age:OR =1.51 (95 ％ CI 0.98-2.32) during 50-59 years,OR =2.10 (95 ％ CI 1.34-3.30) during 60-69 years,and OR =2.63 (95 ％ CI 1.61-4.31) in cases aged over 70 years,as compared to the group aged 40-49 years.The risk in non-manual workers increased about 34 percent OR =1.33 (95 ％ CI 1.04-1.70),compared with manual workers.The risk of MS increased with parity,being OR =1.46 (95％ CI 1.14-1.88),OR =1.78 (95％ CI 1.30-2.43),and OR =1.84 (95％ CI 1.24-2.72),with 2,3,and 4 child-bearings respectively as compared to cases with only one childbearing.The risk of MS was reduced with advancing menopausal age being about 6 percent reduction with each increased year of menopausal age(OR =0.94,95％ CI 0.90-0.99).There was no difference between education,breastfeeding and MS(P＞005).Conclusion Multiple parity,earlier menopausal age,less manual work,and aging seem to be the risk factors of MS in women.

Objective To investigate the association between the neck circumference and central obesity in the elderly.Methods The neck circumference(NC),height,weight,waist circumference (WC) and hip circumference(HC) of 2820 subjects aged over 60 years were detected from some communities in Nanchang.All subjects were divided into different groups,according to the two different obesity indicators of WC and BMI.The relationship between NC and obesity was analyzed.A multiple linear regression analysis was conducted using the Enter method.An R()C curve analysis was employed to judge the tangent point of NC in central obesity.Results The height,weight and BMI were reduced along with age (all P＜0.05),and the waist hip ratio(WHR) was increased along with age(P＜0.01) in the elderly.The NC was decreased along with age in males(P＜0.01),and the WC was increased along with age in females(Pt＜0.01).The NC was longer in males than in females [(36.5±3.0) cm vs.(32.6±2.4) cm,P＜0.01].The NC was increased along with body weight,WC and BMI in the elderly:with each 1 kg increase in body weight,the NC was increased by 0.079 cm in males and 0.139 cm in females;with each 1cm increase in WC,the NC increased by 0.073 cm in males and 0.040 cm in females;with each 1 kg/m2 increase in BMI,the NC increased by 0.121 cm in males and 0.065 cm in females;with 1 year increase in age,the NC was decreased by 0.033 cm in males(all P＜0.05).when obesity was diagnosed according to both BMI and NC,the NC was longer in the obesity group than in the control group,(P ＜ 0.01).The area under receiver operating characteristic(ROC) curve of NC for diagnosing central obesity showed that the area was 0.802 and 0.743 in males and females,and the optimal cut-off value of NC was 36.85 cm and 31.75 cm in males and females,respectively.Conclusions NC is increased along with the increases of body weight,WC and BMI in the elderly.NC is significantly associated with central obesity.NC is more predictive of the central obesity when the value ＞36.85 cm in males and ＞31.75 cm in females.

Objective To investigate the relationships between the neck circumference and cardiovascular risk factors of middle-aged and elder people in a community. Methods Altogether 9 665 community residents ( age≥40 years) were enrolled in the present study. The height, weight, neck circumference, waist circumference, blood pressure, total cholesterol, triglycerides, low density lipoprotein-cholesterol ( LDL-C ) , high density lipoprotein-cholesterol ( HDL-C) , blood glucose, glycosylated hemoglobin, and fasting insulin were measured, and documented in the questionnaire along with other basic information. After adjusted for age, Pearson correlation coefficient was used to analyze the relationship between the neck circumference and the binary variables of cardiovascular risk factors. SPSS16.0softwarewasusedforstatisticalanalysis. Results (1)Theneckcircumferenceswere(37.11±2.79)cm in male and (32. 79 ± 2. 31) cm in female;which were higher in males than females. In both males and females, after adjusted for age, the neck circumference was positively correlated to waist circumference, body mass index, blood pressure, plasma glucose, LDL-C, triglycerides, and insulin resistance, the neck circumference was negatively correlated to HDL-C(all P<0. 05);The neck circumference of males was positively correlated to total cholesterol(P<0. 01);The neck circumference of females was not correlated with total cholesterol(P>0. 05). (2) After adjusted for body mass index and the waist circumference, the neck circumference of males increased with the risk of diabetes ( OR=1. 14, 95% CI 1. 02-1. 28);while the higher neck circumference of females increased the risk of hypertension (OR=1.17,95% CI1.08-1.27),diabetes(OR=1.24,95% CI1.13-1.37),dyslipidemia(OR=1.17,95%CI 1.09-1.27),andinsulinresistance(OR=1.15,95% CI1.06-1.26). Theneckcircumferenceexertedhigher impact on women than it did on men. Conclusion The neck circumference is associated with the cardiovascular risk factors. This association in females is stronger than that in males. The neck circumference seems to be an independent indicator for the cardiovascular risk.

BACKGROUND: How to establish a stable in vitro culture system, including location of corneal limbal epithelial stem cells, in vitro sample harvest, in vitro culture, vector selection, as well as identification methods, play a key role in corneal limbal epithelial stem cells culture. OBJECTIVE: To culture the isolated rabbit corneal limbal epithelial stem cells and to identify the biological properties of cultured cells. METHODS: The primary rabbit cornel limbal epithelial stem cells were isolated and cultured with tissue inoculation using human amniotic membrane as vector. The growth features of cells were observed under an inverted microscope. The morphology of cells was observed by hematoxylin-eosin staining and a scanning electron microscope. Furthermore, the monoclonal antibody AE5 and P63 two-step immunohistochemical staining were used to identify limbal epithelial stem cell protein expression. RESULTS AND CONCLUSION: The rabbit corneal limbal epithelial stem cells could be successfully cultured and maintained a relatively high value-added potential in vitro. Rabbit corneal limbal epithelial stem cells cultured on the amniotic membrane pull netted cellular layer. The AE5 monoclonal antibody positive rate of primary cultured cells was about 5% and P63 monoclonal antibody positive up to 90%. AE5-positive rate increased and P63-positive rate decreased with the increase in the number of subculture. The rabbit limbal epithelial stem cells can be successful culture and amplified on human amniotic membrane in vitro by limbal tissue culture method. The cultured cells maintain the characteristics of corneal epithelial cells. The rabbit corneal limbal epithelial stem cells can form grafts on the amniotic membrane.
