Pigment epithelium-derived factor (PEDF ) was originally found fromretinal pigment epithelium. It is confirmed that it plays an anti-angiogenic and apoptosis role in diabetic microangiopathy. Recently ,PEDF has been found to have a close relationship with insulin resistance ,type 2 diabetes and diabetic macroangiopathy. But the mechanism is unclear. More and more researches focused on its role in oxidative stress. PEDF may become a new target for diabetes and diabetic complication treatment and also a predictive factor for the disease.

74 cases of diabetes insipidus were reported in this paper. There were polydipsia,polyuris and low specific gravity of urine in all patients. Classification was determinedas follows: pituidary 64 cases (including idiopathic 44 cases, secondary 20 cases),nephritic 8 cases and unclassified 2 cases. Intracranial tumors should be paid altentionto rule out. 12 patients responded very satisfactorily to oral administration of singlechlorpropamide. In order to avoid hypoglycemia, an initjal dose of 10 mg/kg/24hr wasrecommended.

Objective To examine the impact of diabetic foot patients′ negative emotion on the caregiver′quality of life. Methods Totally 100 pairs of diabetic foot patients and their caregivers were investigated using convenience sampling method. Results The incidence of anxiety, depression of hospitalized patients with diabetic foot was 41.5% (23/200), 44.0% (88/200) respectively. Pearson correlation analysis showed that anxiety score were negatively correlated with caregivers′ quality of life except for mental health dimension, physical pain dimension and the total score of physical health, mental health and the MOS item Short from Health Survey (SF-36) (r=-0.471--0.117, P<0.05), and depression score were negatively correlated with caregivers′ quality of life except for physical pain dimension and the total score of physical health, mental health and SF-36(r=-0.519--0.220, P<0.05). Multiple regression analysis indicated that caregivers educational level, provided support, social support , relationship with patients, self-evaluation of health, live together time with patient, patient care burden, caregivers gender, depression score, patient age, diabetic foot Wagner grade were the influence factors of the caregiver′ quality of life. Conclusions Diabetic foot patients′ negative emotion has an important impact on caregiver′quality of life, we can improve the quality of life of patients and their caregivers by reducing the negative mood of patients with diabetic foot.

ObjectiveTo investigate the control rate and influence factors of glycolated hemoglobin A1C(HbA1c) of type 2 diabetes in Baoding city community.MethodsA cluster-randomized study was conducted and three communities were selected randomly.The study involved all of people aged 45 years old and above in the three communities.The type 2 diabetic patients diagnosed before,were recorded through the cross section study.Then the questionnaire was finished.All diabetic plasma HbA1c was determined by HPLC method.ResultsEighty-seven patients with HbA1c≤7％ were only 18.6％ in all diabetic patients.As the plasma level of HbA1c increased,occurrences of macroangiopathy and microangiopathy were both increased,by the trend test.Logistic regression analysis showed that therapeutic measures and knowledge about diabetes were main influence factors of achieving the hemoglobin Alc target of ＜7％ in type 2 diabetes.ConclusionThere were low HbA1c control in diabetic patients of Baoding community,and knowing diabetes well and receiving insulin treatment might decrease HbA1c level apparently.

Objective To investigate the inhibition effects of an hTERT-promoter-dependent oncolytic adenovirus Ad-VT that expresses apoptin on human prostatic carcinoma cell PC-3. Methods MTT assay was used to measure viability of PC-3 cell which was infected by recombinant adenovirus.The viability was measured at time points of 12,24,36,48,60,72,84 and 96 h after infection.AO/EB staining,DAPI staining,Annexin V assay were used to investigate the lethal effect and style of Ad-VT on PC-3 cell in vitro.The Caspases were measured by whole cell extraction of PC-3 cells 48hrs after infection. Results Ad-VT,Ad-VP3 and Ad-GT inhibited the proliferation of PC-3 cell in vitro.Ad-VT and Ad-GT were more effective than Ad-VP3 on cell growth,P ＜ 0.05.At 48,72,96 h time points,the inhibition effect of Ad-VT on PC-3 cell exhibited a dose related manner.When infection at MOI 100,the inhibition effect of Ad-VT on PC-3 cells exhibited time related manner.The AO/EB staining,DAPI staining,Annexin V assay,Annexin V assays and Caspase assays showed that Ad-VT inhibited the proliferation of PC-3 cells by inducing apoptosis of prostate cancer cells,Loss of cytoplasmic membrane integrity. Conclusions The hTERT-promoterdependent oncolytic adenovirus Ad-VT could effectively suppress prostate cancer cells PC-3 growth.

In order to achieve the desired effect of cancer treatment, reduce cancer metastasis and recurrence rate, good compliance is essential. In conclusion, this review summarizes the evaluation of compliance, various evaluation tools and their use.

Objective To observe the expression of FGF19 (fibroblast growth factor 19) and PEDF (pigment epithelium-derived factor) in the serum of type 2 diabetic retinopathy (DR) patients and discuss their significance.Methods Total 89 patients with type 2 diabetes were selected and divided into two groups according to whether they were combined with diabetic retinopathy:45 patients with type 2 diabetes alone (DM group) and 44 patients with type 2 diabetes mellitus combined with retinopathy (DR group).At the same time,40 healthy people were selected as the control group (NDM group).The serum levels of FGF19 and PEDF and their biochemical indexes were detected and compared in each group.The correlation between the indexes and the relationship between FGF19,PEDF and DR were analyzed.Results Compared with NDM group,serum FGF19 level in DM group and DR group decreased,while C-reactive protein (CRP) and PEDF level in DM group and DR group increased (P ＜ 0.05);serum FGF19 level in DR group was lower than that inDMgroup,while serum PEDF level was higher than that in DM group (P ＜0.05).The levels of fasting blood glucose (FBG),fasting insulin levels (FINS),glycosylated hemoglobin (HbA1c),total cholesterol (TC),high density lipoprotein (HDL) and low density lipoprotein (LDL) in DM and DR groups were higher than those in NDM group (P ＜ 0.05),but there was no significant difference between DM group and DR group (P ＞ 0.05);the levels of Hcy,triacylglycerol (TG) and CRP in DR group were higher than those in DM and NDM group (P ＜ 0.05),and the levels of VLDL were lower than those in DM and NDM group (P ＜ 0.05).The level of serum FGF19 was positively correlated with HDL and CRP in patients with DR (r =0.341,0.623,P ＜ 0.05),and negatively correlated with fasting blood glucose(r =-0.428,P ＜0.05);The level of serum PEDF in patients with DR were negatively correlated with FINS (r =-0.343,P ＜0.05).When the serum level of PEDF ＞ 12.76 mg/L,the sensitivity and specificity of PEDF dignosing DR were 80.9％ and 56.7％ respectively.Conclusions In patients with DR,serum FGF19 level decreased and serum PEDF levels increased.The level of both changes is closely related to DR and may be involved in the development of DR.

Objective To evaluate the dose distribution of the target volume and the cranial base in nasopharyngeal carcinoma ( NPC ) treated with facial-cervical fields, and to analyze the differences of dose distribution using different isoeenters with the CT-simulator and treatment planning system (TPS). Methods Eleven patients with nasopharyngeal carcinoma were treated by conventional radiotherapy as their primary treatment. All patients were simulated by the conventional simulator and the field borders were marked with thin lead wires on the mask. Then the patients were scanned by the CT-sim with the same immobilization. The planning CT images were transferred to the TPS and the field borders were copied on the DRR, and then GTV and the cranial base were contoured on the coronal CT slices. Two isoeenters were chosen, including one in front of the 1 st cervical vertebra to measeure the depth of the nasopharynx and the other in front of the 3rd cervical vertebra to measure the depth of the upper neck. The prescription dose of 36 Gy was given in 18 fractions. Dose distributions of GTV and the cranial base were calculated with TPS. Results The actual dose of 95% volume of GTV was 33.31 -35.54 Gy (median 34.83 Gy) and 31.43 -33.36 Gy (median 32.44 Gy) when the isoeenters were set in the nasopharynx and the superior neck, respectively. The corre-sponding actual dose of 95% volume of the cranial base was 17.76 - 34.60 Gy ( median 30.28 Gy ) and 16.52 -32.60 Gy (median 28.52 Gy), respectively. Conclusions For NPC patients treated with conven-tional radiotherapy using facial-cervical fields, the actual dose of GTV and the cranial base is lower than the prescribed dose whenever the isocenter is set in the nasopharynx or the upper neck,which is more significant in the latter. The isocenter should be set in the nasopharynx when the conventional radiotherapy is applied and a boost of 4- 8 Gy should be given when the cranial base is involved.

Objective To investigate the distribution of circadian typology of patients with type 2 diabetes mellitus (T2DM) and to analyze its consequent impact on glycemic control. Methods From January 2016 to June 2016, a total of 283 T2DM patients were interviewed in this study. Self designed questionnaire, Morningness-Eveningness Questionnaire (MEQ), Pittsburg Sleep Quality Index (PSQI) and Center for Epidemiological Survey-Depression Scale (CES-D) were used to collect information on diabetes history, circadian typology, sleep quality and depression. HbA1c and other biochemical indicators were determined. The glycemic control target was<7%. The 283 T2DM patients were divided into three groups:morning type group, evening type group and neither type group according to MEQ score. Results Of the 283 subjects, 97 (34.3%) were classified as morning type, 42 (14.8%) as evening type, and 144 (50.9%) as neither. Participants with evening type were younger, shorter diabetes duration, more depressive symptoms, higher perceived sleep debt, higher FBG and higher HbA1c than those with morning type. The binary Logistic regression analysis showed that HbAlc≥7%was associated with higher FBG, higher PSQI score, higher sleep debt, lower HDL-C, and lower MEQ scores (OR=0.189-2.904, all P<0.05). Conclusions Evening type was associated with higher HbA1c and poorer glycemic control in T2DM patients compared with morning type and may be one of the risk factors affecting glycemic control.

Objective To investigate the influence of fear of hypoglycemia on the compliance of diabetes patients.Methods A total of 201 diabetes inpatients with hypoglycemia in four first-class hospital of grade three in Ji'nan were selected by convenience sampling method and investigated by General Information Questionnaire,Chinese version of Hypoglycemia Fear Survey Ⅱ-Worry Scale and Diabetes Treatment Compliance Scale.And carrid on the correlation analysis and the multiple linear regression analysis.Results The scores of fear of hypoglycemia was 3-33 points,the median score was 12 points(interquartile range,10-15 points).The score of treatment compliance was 23-55(35.90±5.84)points.Spearman correlation analysis showed that fear of hypoglycemia score were negative correlated with treatment compliance score,drug,diet,exercise dimensions(r=-0.467-0.288),and it was positively correlated with self monitoring dimension(r=0.259),the difference was statistically significant(P＜0.01),it was not associated with periodic inspection dimension.Multiple linear regression analysis showed that the economic income,occupation,whether to participate in health education of diabetes mellitus,glycosylated hemoglobin,fear of hypoglycemia were the influence factors of treatment compliance.Conclusions Diabetes patients'fear of hypoglycemia can influence treatment compliance.medical staff should pay attention to and take effective measures to reduce their fear of hypoglycemia and improve treatment compliance.
