This animal experiment was aimed at the questions whether high glucose concentration inhibits insulin secretion (glucose toxicity, GT) of beta-cell of islets from SHR and Wistar-Kyoto (WKY) rat and whether adrenomedullin (AM) enhances GT. Ten 6-week-old SHRs (test group) and ten 10-week-old Wistar-Kyoto rats (WKY) (control group) were selected. RAMI-1640 medium containing 5.6 mM glucose (normal glucose group) and 20 mM glucose (high glucose group) were applied. Various concentrations of AM (0, 10(-8), 10(-7), 10(-6) M) and RPMI-1640 medium containing high glucose were mixed, respectively. The isolated islets from rats were put into 12-well plates (90 islets/well). The islets were incubated in RAMI-1640 medium containing normal or high glucose for one hour. Then the supernatants from both incubations were determined by RIA for insulin. In SHR group, the insulin concentration in supernatants gained from high glucose group without AM was lower than that from normal glucose group (19.9+/-6.6 vs 60.9+/-33.6 mU/L, P<0.05). With the increment of the concentration of AM, insulin concentration in supernatants from islets incubated in high glucose and various concentrations of AM tended to be low further (19.9+/-6.6 vs 22.2+/-8.0 vs 21.5+/-5.6 vs 17.9+/-3.6 mU/L). The changing tendency in control group was the same as in SHR group. When the islets were incubated in normal glucose and high glucose medium, the insulin concentration in supernatant significantly decreased in SHR group compared with that in control group (P<0.01). The insulin secretion was inhibited by high glucose in beta-cell of islets from SHR and WKY. The results suggest GT to beta-cell of islets from SHR and WKY. AM tended to inhibit insulin secretion in a dose-dependent manner in beta-cell of islets from SHR and WKY. The inhibition of insulin secretion caused by high glucose in beta-cell of islets from SHR was more remarkable than from WKY. This may be related to secretion dysfunction in beta-cell of islets from SHR.

Recently some studies have showed that bone strength may avoid the misdiagnosis and missed diagnosis of osteoporosis(OP) by bone mineral density (BMD) alone. It was found that corrected bone mineral content (cBMC) was well correlated with bone strength. In this study bone strength was replaced by cBMC to compare it with BMD, and evaluate whether BMD has limitations in the diagnosis of OP in obese individuals. one hundred and two healthy subjects in the community with the body mass index (BMI) between 25 and 39 kg/m2 were enrolled. There were 31 males and 71 females with a mean age of 37.2 +/- 9.4 years. Their BMD and BMC of lower limbs, trunk and the whole body were measured with dual energy X-ray absorptiometry (DEXA). cBMC was expressed by BMC divided by weight. Intra abdominal fat area (IAFA) was measured by CT scan at the level between 4th-5th lumbar vertebra. Linear correlation analysis with SPSS 10.0 soft pack was used for statistics. The results showed that there was a positive correlation and tendency between body weight, BMI and BMD values of lower limbs, trunk and the whole body. However, negative correlation and tendency were demonstrated between body weight, BMI and cBMC, between IAFA and BMD of lower limbs, trunk and the whole body and between IAFA and cBMC as well. We found that the tendency of changes of cBMC and bone strength was similar. So we suggest in certain extent that cBMC could replace bone strength in the diagnosis of OP in obese individuals.

Objective To investigate the level of occupational burnout and mindfulness among undergraduate nursing in-terns, and to analyze their relationship. Methods For convenient sampling, 600 nursing students who belong to 4 colleges and universities of Henan were investigated using the general information questionnaire, the Chinese version of Maslach Burnout Inventory (MBI) and Mindfulness Attention Awareness Scale (MAAS). Results The scores of occupational burnout were as follow: the score of emotional exhaustion was (33.46 ± 9.31) points, the score of depersonalization was (14.26 ± 5.91) points, the score of low personal achievement was (17.58 ± 8.49) points, the score of mindfulness was (57.27 ± 13.41) points. Mindfulness had a significant negative effect on job burnout, emotional exhaustion and low personal achievement. Level of mindfulness, language violence and work overtime in-terns, and possible of clinical nursing work in the future were the main factors influencing job burnout, and three factors could explain 25.4％ of job burnout. Conclusions Mindfulness had a significant negative effect on job burnout. Nursing educators and administrators should improve the level of mindfulness of nursing students to reduce their job burnout.

Objective To investigate the state of the aging perceptions and quality of life in the elderly patients with hypertension in Kaifeng city and their relationship. Methods A total of 156 elderly patients with hypertension in Kaifeng city were investigated by using a general data questionnaire, Chinese version of the Aging Perceptions and SF-36 quality of life assessment scale. Results The scores of the aging perceptions were higher than the median. The score of negative control was the highest with (3.72 ± 0.47) points, and the score of emotion representation was the lowest with (2.59±0.65) points. The scores of physical function, role limitation due to physical health, bodily pain, general health perception, emotional function and mental health of the elderly patients with hypertension were significantly lower than that of normal population (t=-17.074--3.492, P<0.01). Pearson correlation analysis showed that positive control, positive outcome, and recognition were significant positively correlated with quality of life (r=0.221- 0.352, P<0.05); acute/chronic time, emotional representation and negative result were significant negatively correlated with quality of life were presented (r=-0.478--0.310, P<0.01);periodic time was significant negatively correlated with mental health status (r=-0.314, P<0.01). Conclusions There is a significant correlation between the aging perceptions and quality of life in elderly hypertensive patients in Kaifeng city. The quality of life was significantly lower than that of normal population in China, and it was affected by the aging perceptions.

Objective To investigate the diabetic foot occurrence and influence factors of the type 2 diabetes patients in order to provide the reference for the prevention and treatment of diabetic foot. Methods Three hundred and fifty-seven type 2 diabetes patients treated in the endocrinology department of our hospital from June 2012 to June 2014 were chosen as the research objects, the clinical data of them were collected by self-made questionnaire after consult-ing a large number of references. The clinical data was analyzed by descriptive statistics and binary classification logis-tic regression analysis of SPSS19.0 statistical package to find out the occurrence and influence factors of diabetic foot in type 2 diabetes patients. Results The diabetic foot incidence of type 2 diabetes patients was 6.44%(23/357). Multi-ariable Logistic regression analysis revealed that high degree of culture (β=-1.26, P=0.000), the degree of the related knowledge of diabetic foot (β=-1.44, P=0.000) and PDCA cycle management of diabetic foot (β=-1.68, P=0.000) were the postoperative factors of type 2 diabetes patients complicated with diabetic foot, abnormal glycosylated hemoglobin (β=1.16, P=0.000) was a risk factor for type 2 diabetes patients complicated with diabetic foot. Conclusion The diabetic foot incidence of the type 2 diabetes patients is high, it is affected by many factors. In clinical medical process, we should strengthen health education and blood glucose monitoring,and then optimize the prevention countermeasures for diabetes in order to effectively control the patients' blood sugar, reduce the occurrence of diabetic foot and improve the prognosis of patients.

Despite the deepening of research on breast cancer,improving of treatment techniques,there are still many patients will appear local-regional recurrence after surgery.For patients with local recurrence after radical mastectomy,according to whether the postoperative radiotherapy performed,prognosis and treatment protocols are absolutely different.As for patients with local recurrence after breast-conserving surgery,more and more studies have shown that lumpectomy (secondary breast conserving surgery) combined with brachytherapy can achieve a similar effect with radical surgery in recent years,so it is a worth considering treatment protocol.

Objective To study the effects of Puerarin(Pue)on survival rate,expression of GAP-43 and NGF in spinal motoneurons following brachial roots avulsion. Methods From March, 2014 to December, 2015, 192 adult Sprague Dawley rats were divided into four groups: Avulsion, Pue 50 treatment, Pue 100 and Pue 200 groups. The right C5-C7nerve roots were avulsed through the methods of cervical dorsal approach. Puerarin or normal saline was given immediatedly once daily to the rats respectively by the intraperitoneal injection. The rats were killed at 1, 2, 4 and 6 weeks after injury. The paraffin sections of C7 segment were stained with neutral red. Expression of GAP-43 and NGF were detected by Western blot. Results Compared to the avuled group, the motoneuron survival rates of Pue 100 and Pue 200 dose treatment groups increased on the second week and the sixth week(P < 0.05 or P < 0.01), and the Pue 200 dose treatment group increased on the fourth week(P < 0.01).In the anterior horn of all three groups, expression of GAP-43 increased from the 1st week to the 6 week after the operation, and reached the peak at the 4th week, and decreased at the 6th week. Compared to the avuled group, expression of GAP-43 protein increased in the Pue 100 and Pue 200 dose treatment groups at the 1st week and 2nd week,the expression of NGF protein increased in the three Pue treatment groups at four time points(P < 0.05 or P < 0.01). Conclusion Puerarin can improve the survival rates of spinal motoneurons after the brachial plexus root avulsion, and the expression of GAP-43 and NGF increased, suggesting that Puerarin may play an role in the repair of brachial plexus avulsions by promoting the ex-pression of nerve growth factors.

Objective: To explore the application of septoplasty and cheiloplasty in complete unilateral cleft lip repairment, and evaluate the effect on nasal shape correction. Methods: Twenty-four infants with complete unilateral cleft lip were divided into two groups: the correction group and the control group. Both groups underwent cheiloplasty by Mohler′s technique, septoplasty was performed in the correction group during the primary cheiloplasty. Six-month follow-up was taken to evaluate the nasal shape with the three dimensional images. Independent-samples t Test was performed using SPSS 21.0, to compare the nasal morphology between two groups. Results: All patients healed in the first stage, and were followed for 6 months after operations. There were no complication, including nasal septum perforation, occurred in either group.There were statistically significant differences in nasal parameters between the correction group and controls (P<0.05). The columellar width, nostril width on the affected side, and columella deviation of the correction group were smaller, than those of controls. The nose tip height, columellar height and nostril height on the affected side of the correction group were greater than those of the control group. Conclusions Septoplasty associated with the primary cheiloplasty in complete unilateral cleft lip repairment, shows better results in the elongation of the nasal columella, and the correction of septum deviation, and provides a stable nasal structure.

Objective:To evaluate the data quality of Shenzhen Type 1 Diabetes Alliance (SZT1D), and to provide a basis for evaluation and improvement for the continuous improvement of data quality.Methods:From December 2018 to July 2021, 697 first-visit type 1 diabetes (T1DM) patients (including 501 in Shenzhen and 196 out-of-Shenzhen) and 120 re-visited T1DM patients (including 113 in Shenzhen and 7 out-of-Shenzhen) who were registered by SZT1D in collaborative research platform network of China Type 1 Diabetes Alliance (hereinafter referred to as China T1D). The data quality was evaluated from three dimensions: data completion, accuracy and revisit. The data completion degree was evaluated by the overall data completion degree and the key indicator completion degree; the data accuracy was evaluated by the probability of abnormal blood glucose value; the patient′s return visit was evaluated by the return visit rate.Results:The main characteristics of T1DM in SZT1D were young and middle-aged adults [age: (34.4±17.1)years] with thin body [BMI: (19.80±3.52)kg/m 2)], half of male and female patients [proportion of male: 52.4%(365/697)]; the main types of diagnosis were classical T1DM [65.22%(150/230)] and latent autoimmune diabetes in adults(LADA) [26.08%(60/230)], and the fasting blood glucose (FPG) [(10.93±6.98)mmol/L] and glycosylated hemoglobin (HbA 1c) [(10.63±3.01)%] were high. The average completion rate of the overall data of the first diagnosed patients in SZT1D was only 60% [(62.9±31.5)%]: the number of patients with overall data completion ≥80% in SZT1D was only 50.2%(350/697); the number of patients with overall data completion ≥80% in Shenzhen was less than that outside Shenzhen [44.3%(222/501) vs 65.3%(128/196), P<0.001]. The key indicators with better completion rate of first-visit were disease course [76.2%(531/697)], age of onset [75.8%(528/697)], family history of diabetes [74.9%(522/697)], etc., but none of them had a completion rate of more than 80%, and the diabetes self-management behavior assessment questionnaire and scale score were completely missing; the frequency of daily blood glucose monitoring [46.1%(231/501) vs 64.3%(126/196), P<0.001], current insulin regimen [44.3%(222/501) vs 63.3%(124/196), P<0.001], number of diabetic ketoacidosis (DKA) since the onset of the disease [45.7%(229/501) vs 64.8%(127/196), P<0.001] and the number of symptomatic hypoglycemia in the past 1 month [39.3%(197/501) vs 63.8%(125/196), P<0.001] were higher in Shenzhen than those reported outside Shenzhen. In addition, the probability of abnormal FPG and postprandial glucose (PPG) [5.2%(24/466); 3.8%(19/236)] were low. The revisit rate was not high [17.2%(120/697)], and the revisit rate in Shenzhen was higher than that outside Shenzhen [22.6%(113/501) vs 3.6%(7/196), P<0.001]. The first revisit rate was 16.2%(113/697) and the second revisit rate was seriously insufficient [1.0%(7/697)]. Conclusions:The data quality of T1DM patients recorded by SZT1D needs to be further improved. Improving the information interconnection between China-T1D and SZT1D, employing quality control personnel and building a systematic data quality evaluation analysis and feedback mechanism are methods to promote the comprehensive, accurate and efficient input of T1DM data and continuously improve the evaluation methods to improve the overall data quality.
