Objective To investigate the effects of WeChat follow-up of relatives on knowledge cognition, change of behavior, visual acuity and blood glucose for diabetic retinopathy (DR) patients.Methods Totally 107 typeⅡdiabetic patients from January 2014 to December 2015 in the Department of Endocrinology were enrolled in the study, with the inclusion criteria of 60 years of age and older and diagnosed with diabetic retinopathy. Subjects were divided into the WeChat group (53 cases) and the control group (54 cases) based on the order of enrollment. The control group was given routine care and health education, while the WeChat group was given additional follow-up of relatives through WeChat with distribution of health education messages for the management of DM and DR once each week for 12 months. Questionnaires were used to collect information on patient's knowledge of DR prevention & treatment and behavior change, FBG, PBG, and HbA1c, and visual acuity were also collected to assess the effectiveness of the intervention. Chi-square test was used to compare the patients' cognitive rate, behavioral change and stage of retinopathy. The t-test was used to compare fasting blood glucose, 2 hours postprandial blood glucose, glycosylated hemoglobin and visual acuity. Results Cognitive Knowledge change on DR were analyzed for the following questions:the time of the first fundus examination after diagnosis of diabetes and occurrence of systemic complications; what are key measures for prevention of early blindness in patients with DR;fundus checkup requirements while blood glucose control is ideal;types of major eye complications for diabetic patients; when laser treatment should be done for DR patients; how long apart should patients check the fundus;what is the normal range of blood glucose;and the types of server damages of DR;etc. The cognitive rates of WeChat group after follow-up were as follows 88.7%, 67.9%, 56.6%, 96.2%, 79.2%, 67.9%, 69.8%, 94.3%, 75.5%. WeChat group compared with the Control group after follow-up (χ2 values were 16.77, 30.76, 16.30, 7.75, 9.68, 36.03, 9.25, 10.57and 9.41, respectively, all P<0.01), the difference was statistically significant. The results of WeChat group before and after the follow-up were (χ2 values were 19.41, 38.22, 17.90, 8.23, 9.34, 38.22, 21.81, 12.08 and 25.52, respectively, all P<0.01), the difference was statistically significant. The cognitive rate for DR risk factors for the WeChat group was 24.5% before follow-up and 43.4%after follow-up;the after follow-up difference between WeChat group and the Control group was statistically significant (χ2=5.33, P<0.05). WeChat group before and after follow-up comparison (χ2=4.21, P<0.05) was also statistically significant. For values of fasting blood glucose, 2 h postprandial blood glucose and glycosylated hemoglobin, results of WeChat group before follow-up were as follows (13.18± 4.46) mmol/L, (16.17 ± 3.97) mmol/L, (10.18 ± 2.76)%;results of WeChat group after follow-up were (8.45 ± 2.26) mmol/L, (11.34 ± 2.34) mmol/L,(7.83 ± 1.40)% respectively. The after follow-up comparison between WeChat group and the Control group showed statistically significant differences (t values were-7.06,-7.30, and-6.37, respectively, all P<0.01). Within the WeChat group, before and after follow-up comparison were all significantly different (t values were 6.83, 7.59 and 5.54, respectively, all P<0.01). The vision of WeChat group before follow-up was 0.68 ± 0.18, after follow-up was 0.71 ± 0.20. There were no significant differences in the two groups after follow-up, before and after follow-up WeChat group, the Control group before and after follow-up about visual acuity comparison (t values were 1.02,-1.10, and 0.57, respectively, all P>0.05). The two groups of patients were compared in balanced diet, regular eating time, meal volume, wearing loose clothing and exercise shoes and socks before each exercise, exercising for more than 30 min, weekly checkup of blood glucose, blood sugar test before and after the exercise and other measurements of behavior changes were significantly different (χ2 values were 11.54, 11.77, 13.68, 5.89, 10.23 and 8.72, respectively, all P<0.01 or 0.05). There were no significant differences in self-withdrawal of medication and Retinopathy stageⅠand stageⅡpatients and between these two patient groups (χ2 values were 1.20, 0.01 and 0.01, respectively, all P>0.05). Conclusions The practice of WeChat follow-up of relatives can improve cognition ability for DR patients aged 60 years and older, it can promote the healthy behavior and the BG monitoring effectively.

Cardiovascular and cerebrovascular diseases, including coronary heart disease, periph-eral vascular disease and atherosclerosis, are the first cause of death worldwide. The pathogenesis of atherosclerosis is a complex process that involves a number of cellular processes and molecular mecha-nisms, such as disorder of lipid metabolism, inflammatory cell infiltration, oxidative stress, vascular en-dothelial cells injury and activation of smooth muscle cells. Their interaction eventually leads to plaque rupture and thrombus formation, causing serious cardiovascular and cerebrovascular events. Chinese medicine has displayed rich anti-AS activities and clinical applications. This review summarizes the anti-atherosclerosis effects and possible mechanisms of Chinese medicine in regulating lipid metabolism, anti-inflammation and antioxidation, protecting endothelial cells, inhibiting the proliferation and migration of smooth muscle cells, improving coagulation and fibrinolysis systems and stabilizing the plaque.

Results The average detective rate of Clonorchis sinensis antibodies was 3.92％ (17/434),the detective rate of Clonorchis sinensis in residents of fishermen area, cooks and shopkeepers (6.45％ ,2/31,5.59％ ,9/161、4.29％ ,3/70)was obviously higher than that of in the normal control group(0. 86％ ,1/115). There was a significant difference in the statistics (X2 = 3.52,X2 = 4.01,X2 = 2.28,P＜0. 01 ). Conclusions ①There is human infection of Clonorchis sinensis in Nantong area. ②The data emphasizes that the infection of Clonorchis sinensis has a strong association to do with occupation and contacting with raw fishes and opportunity of eating raw fishes and shrimps. ③It is recommended that the people of common eating raw fishes and shrimps must be examined and treated regularly.

Objective:To highlight the key points of primary culture of human nasal epithelial cells by enzymatical dissociation for high achievement ratio,and to establish a successful primary culture model for subsequent experiments.Method:Primary culture of human nasal epithelial cells was performed with enzymatical dissociation of isolated tissue in serum-free medium. On the basis of this method,some improvements were subjected,such as stripping mucosal epithelium from adjacent connective tissue,applying DNase type Ⅰ to digesting procedure,adding trypsin directly to the collagenase solution containing digested mucosa pieces,employing uncoated culture dishes and so on. Immunofluorescence with a monoclonal anti-cytokeratin antibody 8/18 was used to confirm the epithelial nature of the cultured cells. Result:Nasal epithelial cells grew well and confluenced on the 6th to 8th day. Positive expression of cytokeratin(CK)8/18 showed the epithelial property of cultured cells.Conclusion:Primary culture model of human nasal epithelial cells can be successfully established by enzymatical dissociation. Improvements on processes of material using and enzyme digestion can gain a high achievement ratio and harvest a high purity and certain amount of reliable primary epithelial cells.

ObjectiveTo explore the risk factors for the prognosis of respiratory failure in neonates with gestational age≥34 weeks. MethodsA total of 143 hospitalized neonates with respiratory failure who had gestational age≥34 weeks were enrolled from Jan. 2011 to Jun. 2013. According to the outcome, the neonates were divided into good prognosis group and poor prognosis group. The risk factors for the prognosis of respiratory failure were screened by univariate analysis and mul-tivariate binary logistic regression model.ResultsAmong the 143 neonates, 105 neonates had good prognosis and 38 neonates had poor prognosis. Univariate analysis showed that the mode of delivery, small for gestational age, 5 minutes Apgar score <7, and with primary disease being pneumonia/sepsis were associated with a poor prognosis. The differences were statistically signif-icant (P<0.05). Furthermore, the multivariate binary logistic regression model showed that, small for gestation age (OR=23.87, 95%CI:3.149-180.9) and pneumonia/sepsis (OR=2.996, 95%CI:1.514-5.928) were the independent factors of poor prognosis. ConclusionsSmall for gestation age and primary diseases being pneumonia/sepsis are the independent factors inlfuencing prog-nosis of respiratory failure in neonates born at a gestational age≥34 weeks.
