Objective To explore the possible anti-inflammatory mechanism of intensive insulin therapy （IIT） by studying the effect of IIT on the levels of TNF-α, IL-6, C-reactive protein （CRP） and APACHE Ⅱ score in biliary pyemia. Methods Twenty eight patients with biliary pyemia who were admitted by our department and given an operation within 24 h form Jan. 2005 to Dec. 2008 were randomly divided into two groups by using random number table numbers: one group treated with IIT （IIT group, n=14） and another group treated with routine insulin therapy （RIT group, n=14）. The inflammatory factors, such as TNF-α, IL-6 and CRP were detected dynamically and the APACHEⅡ score was calculated. ResultsThe level of CRP and APACHEⅡ score on day 5 and 7 and the levels of TNF-α and IL-6 on day 3, 5 and 7 after operation in IIT group were significantly lower than those in RIT group （P＜0.05, P＜0.0１）. Compared with preoperative levels, the IL-6 and APACHEⅡ score in IIT group commenced to decrease on day 3 after operation （P＜0.05）, that was earlier than control group. Conclusion The treatment with IIT can suppress the composition of TNF-α, IL-6 and CRP, protect impaired hepatic cells, and reduce APACHEⅡ score, the degree of systemic inflammation and incidence of MODS.
ObjectiveTo explore the morbidity rate and risk factors of proliferative diabetic retinopathy (PDR) in type 2 diabetes.MethodsThe clinical data of patients, with PDR in 2739 consecutive cases of type 2 diabetes diagnosed in this hospital from 1994 to 2001 were analyed retospectively. The diagnosis of diabetic retinopathy (DR) was confirmed by ophthalmoscopy and fundus fluorescein angiography (FFA). Blood pressure, fasting and postprandial blood sugar, glycosylated haemoglobin（HbA1c）, total serum cholesterol, triglyceride, creatinine, and albumin excretion rate were measured.ResultsThe morbidity rate of type 2 DR was 27.8%（761/2739）, and the morbidity rate of PDR was 4.2%（114/2 739） occupying 15% of the patients with DR. The duration, fasting blood sugar, glycosylated haemoglobin, blood pressure and albumin excretion rate were much higher than those in the control（P＜0.01, glycosylated haemoglobin P＜0.05）. The independent risk factors of PDR were duration of the disease （r=0.15, P＜0.01） and albumin excretion rate （r=0.08, P＜0.05）. The risk factors of PDR were albumin excretion rate and fasting blood sugar (r=0.13, P＜0.05) in patients with longer duration(≥5 years). The morbidity rate of PDR was 2.3%, 5.9% and 12.4% in patients with duration less than 5 years, 5 to 10 years and over 10 years groups, respectively. The morbidity of PDR of the patients in normal albuminuria, microalbuminuria and overt albuminuria group was 2.1%、5.3% and 18.8% respectively.ConclusionsType 2 diabetes accompanied with PDR is relative to the duration of the diabetes, albumin excretion rate, fasting blood sugar, blood pressure, and glycosylated haemoglobin, in which the duration of the disease, albuminuria and fasting blood sugar are the risk factors of occurance of PDR.

Objective
To investigate the relationship between dyslipidemia and diabetic retinopathy in non-insulin-dependent diabetes mellitus（NIDDM） patients．
Methods
In 55 health controls，60 NIDDM patients with DR and 75 NIDDM patients without DR，the plasma total cholesterol（TC），triglycerides（TG），high-density lipoprotein（HDL）and HDL subfractions，fasting plasma glucose（FPG），fasting plasma insulin（FINS）and glycosylated hemogolbin（HbA 1C）were measured，and the plasma lowdensity lipoprotein （LDL） and very lowdensity lipoprotein（VLDL）were caculated．
Results
In NIDDM patients with DR，the TC，LDL，FPG，HbA 1C and duration of NIDDM were higher or longer than those in NIDDM patients without DR．Moreover，the TC，LDL，FPG、FINS、HbA 1C and dutation of NIDDM were increased or lengthened in NIDDM patients with proliferative DR as compared with those with backgroud DR．The correlation analysis showed the severity of DR was positively correlated with TC，LDL，HbA 1C and duration of NIDDM．
Conclusion
Dyslipidemia may play some role in the onset and development of DR．

Objective
To explore the correlation between blood glucose and self-management behaviors in patients with type 2 diabetic mellitus before initial basal insulin therapy.
Methods
A convenient sample of 200 patients with type 2 diabetic mellitus who were hospitalized in a tertiary hospital from February to August 2016 were enrolled in the study on a voluntary basis. Patients’ demographic information, fast blood glucose, glycosylated hemoglobin, and scores of diabetes self-care activities were gathered through questionnaires.
Results
A total of 193 valid questionnaires were recovered. Before starting basal insulin therapy, the mean blood glucose and the mean glycosylated hemoglobin of the 193 patients were (12.22±3.95) mmol/L and (10.01±2.38)%, respectively, with 12 patients (6.22%) meeting the goal of fasting blood glucose ≤7 mmol/L and 18 patients (9.33%) meeting the goal of glycosylated hemoglobin <7%, respectively. The total score of self-care activities was 26.76±14.77, in which 3 patients (1.55%) performed well. Spearman analysis demonstrated that the total score of self-care activities was negatively correlated with fast blood glucose ( r=–0.401, P<0.001) and glycosylated hemoglobin (r=–0.227, P=0.028).
Conclusions
The blood glucose levels and self-management behaviors in diabetic patients at the beginning of initial basal insulin therapy are not optimistic. Enhanced management of type 2 diabetic patients with initial basal insulin therapy is the prerequisite to promote diabetes self-care activities.
ObjectiveTo observe expressions of E3 ubiquitin ligase—mitsugmin53 (MG53) protein, MG53 mRNA, and insulin receptor substrate 1 (IRS-1) mRNA in skeletal muscle of non-obese type 2 diabetic mellitus (T2DM) rats after gastric bypass operation (GBP), and to investigate possible mechanism of GBP in improving insulin resistance.MethodsTwenty-four healthy male GK rats were randomly divided into diabetic operation group, diabetic sham operation group, and diabetic control group, 8 rats in each group; besides, 8 male Wistar rats were served as normal control group. The expressions of MG53 protein in skeletal muscle tissue were detected by using Western blot method on week8 after operation. The mRNA levels of IRS-1 and MG53 in skeletal muscles tissue were measured by RT-PCR methods on week 8 after operation.Results① The expressions of MG53 protein and MG53 mRNA in the diabetic sham operation group and diabetic control group were significantly higher than those in the diabetic operation group and the normal control group on week 8 after operation (P<0.05), respectively, which had no significant differences between the diabetic operation group and the normal control group (P>0.05), and between the diabetic sham operation group and the diabetic control group (P>0.05) on week 8 after surgery. ② Compared with the normal control group, the expression of IRS-1 mRNA was significantly decreased in the diabetic operation group, the diabetic sham operation group, and the diabetic control group (P<0.05), while there were no significant differences between the diabetic operation group, diabetic sham operation group, and the diabetic control group on week 8 after operation (P>0.05).ConclusionExpression of E3 ubiquitin ligase—MG53 protein in skeletal muscle tissue in T2DM rats following GBP is decreased, thus reduces the IRS-1 ubiquitin-degradation, increase the expression of IRS-1 protein in insulin signaling pathway of skeletal muscle tissue, and improve insulin resistance of skeletal muscle.
Mechano growth factor (MGF) is an autocrine/paracrine factor and sensitive to mechanical stimulation. MGF can be highly expressed in various soft tissues under physical stimuli, biochemistry stimuli or in damaged situation. MGF may "compensate" the stress for tissue in the processing of tissue repair. MGF can effectively accelerate the repair of the soft tissue by promoting the proliferation, migration and differentiation of cells. This paper summarizes the MGF expressions in different soft tissues and their functions in soft tissue repair. The paper also discusses current problems and challenges in using MGF to repair the soft tissue.
Objective Through studying a diabetic patient accompanied with pancreatic cancer by means of evidence-based clinical practice, to find out the relationship between diabetes mellitus and cancer and whether the long-acting insulin glargine increases the risk of cancer or not, which is regarded as a disputable hot issue at present. Methods Such databases as The Cochrane Library (Issue 3, 2010), OVID-EBM Reviews (1991 to Sept. 2010), MEDLINE (1950 to Sept. 2010) and CNKI (2000 to Sept. 2010) were retrieved to collect high quality clinical evidence, and the best therapy was formulated in accordance with the willingness of patients themselves. Results Eight randomized controlled trials (RCTs), four meta-analyses and one RCT meta-analysis were included. The evidence indicated that: a) Diabetes mellitus was kind of related to the occurrence of malignancies; b) There was no evidence at present showing the relationship between long-acting insulin glargine and cancer; c) Strictly controlling of blood sugar did not increase the risk of tumorigenesis, but hyperglycemia causing cancer was proofless; and d) Whether the diabetic patient with cancer should stop taking long-acting insulin glargine or not should require suggestions from specialists rather than patients themselves. Conclusion No evidence at present shows that tumorigenesis is related to diabetes mellitus, long-acting insulin glargine and strict controlling of blood sugar. It is necessary to require more evidence to decide whether the therapy should be adjusted or not for the diabetic patient with cancer who is in the process of glargine therapy.
Objective To assess the effectiveness and safety of biphasic insulin aspart 30 given three times a day in the management of type 2 diabetes. Methods Such databases as CENTRAL, MEDLINE, PubMed and CNKI were searched on computer; additionally, the relevant conference proceedings from associations like American Diabetes Association, and the references of all selected literatures were also hand-searched. The randomized controlled trials (RCTs) on biphasic insulin aspart 30 given three times a day in treating type 2 diabetes were screened according to inclusive and exclusive criteria, without concerning the limitation of languages and blind methods. After data extraction and quality evaluation, Meta-analysis was performed by using RevMan 4.2 software. Results Ten trials involving 1 415 patients were included. The sub-group analysis showed that compared with the group of given biphasic insulin aspart 30 twice a day (the bid group), the group of given biphasic insulin aspart 30 three times a day (the tid group) was superior in decreasing HbAlc (Plt;0.000 01). Compared with the group of thrice preprandial injection of Novolin R plus one injection of Novolin N at bedtime (the qid group), Meta-analysis showed that, a) As to the average fasting glucose levels: the tid group was not superior to the qid group (P=0.65); b) As to the average 2-hour postprandial glucose levels: the tid group was superior to the qid group (P=0.0003); c) As to the therapeutic time: the tid group was not superior to the qid group (P=0.38); d) As to the insulin doses: the tid group was superior to the qid group (P=0.000 1); e) As to the insulin costs: the tid group was inferior to the qid group (P=0.02); and e) As to the incidence of hypoglycaemia: the tid group was superior to the qid group (P=0.000 2). Compared with the oral antidiabetic drugs, the results of Meta-analyses showed: the tid group was superior in decreasing HbAlc (P=0.001). Conclusion The limited current evidence shows that biphasic insulin aspart 30 given three times a day, as a simple insulin intensified scheme, is safe and effective for type 2 diabetes, and is worth recommending in clinic. However, all these findings should be further confirmed with more large sample and well-designed RCTs.
Diabetes and its complications pose a serious threat to human life and health. It has become a public health problem of wide concern worldwide. Currently, diabetes is mainly treated with insulin injection in clinic. However, manual insulin injection still has many shortcomings. In recent years, with the deepening of research, it has been found that an automated insulin delivery system (AID), which combines a continuous glucose monitoring device with an insulin pump, can significantly improve the effectiveness of diabetes treatment and reduce the incidence of complications in patients. This paper firstly introduces the composition of the AID system and its working principle, and then details the development history and current status of the related technologies from the aspects of continuous glucose monitoring technology, insulin pumps and the development of closed-loop control algorithms, etc. Finally, this paper looks forward to the application prospect and future development of AID system in the field of diabetes treatment, providing theoretical reference for further research.
Since the release rate of protein in hydrogels is directly dependent upon the size of the protein and the hydrogel, how to deliver low molecular weight protein for prolonged periods has always been a problem. In this article, we present a usage of self-assembling peptide (P3) with the RGD epitope on its N terminus. The concentration of the released insulin-like growth factor 1 (IGF-1) was determined by UV-vis spectroscopy and the release kinetics suggested a notable reduction of the IGF-1 release rate. Cell entrapment experiments revealed that IGF-1 delivery by biotinylated nanofibers could promote the proliferation of the mouse chondrogenic ATDC5 cells when compared with cells embedded within nanofibers with untethered IGF-1.
