Objective To explore the application effect of interactive health education in insulin injections of aged patients with type 2 diabetes in the incipient stage of diagnosis and treatment. Methods 100 cases of aged patients with type 2 diabetes were hospitalized into endocrinology department from January 2014 to December 2014, the pen insulin injections were conducted for them at the beginning. They were equally divided into experimental group and control group through random number method. And, the general education guidance was conducted in control group. Meanwhile, the diabetes health education team was established in observation group on the basis of control group. Then, it was educated through the interactive lectures, interviews, teaching, repeated teaching, psychological intervention and individual assessment. Before and after education, the KAP survey of standard insulin injections were used for the patients in two groups to evaluate their degree of proficiency in the knowledge and skills about insulin injections, and the incidence of glucose metabolism level and low blood sugar. Results After intervention, the insulin injection skill in observation group was better than that of in the control group, (64.6%,31/48 vs. 24.5%, 12/149,χ2=16.441, P<0.01), while the level of glycosylated hemoglobin was reduced from (7.95±0.65)%to (6.58±0.62)%(t=7.85, P<0.01). Conclusions In the incipient stage of diagnosis and treatment, the ability of aged patients with type 2 diabetes in learning new knowledge and technology was improved through interactive health education mode. Besides, the insulin injections were standardized. Also, the glucose metabolism was improved, and the incidence of hypoglycemia was significantly reduced to ensure the patients′safety when the insulin was injected outside hospital, which was worth being clinically applied and promoted.

Objective To observe the distribution of oligodexynucleotide (ODN)MT01 in main organ tissues of the rats at different time points and to discuss the regularity of the distribution of MT01 preliminarily. Methods 60 male Wistar rats were randomly divided into experimental group(n=30)and control group(n=30). The rats in experimental group was locally injected with Cy5 labeled MT01 in gingival mucosa,whereas the rats in control group were injected with MTO1.The samples of rat lung,liver spleen,kidney,heart,and brain tissues were collected at 15 min,1 h,4 h,8 h,16 h,1 d,2 d,3 d,4 d,and 5 d after injection,and the distribution of MT01 fluorescence was observed by laser scanning confocal microscope.The ratio of fluorescence positive cells indicated the amount of MT01 that had been taken up by different organs.Results No positive fluorescence cells were observed in control group.Whereas,in experimental group ,the positive fluorescence cells were detected in the tissue samples of lung,liver,spleen and kidney but not in the tissue samples of heart and brain.The positive fluorescence cells distributed focally in kidney tissue and presented primarily in the cytoplasm of renal tubular epithelial cells.The ratios of positive fluorescence cells changed regularly with time in liver, spleen and kidney tissues and the highest level was detected at 4,3 and 4 d after injection.No distinct regularity of the ratio of positive fluorescence cells was observed in lung tissue.Conclusion MT01 can be taken up by liver,spleen and lung tissue and primarily by kidney with regularity in distribution.

Objective:To investigate the effect of MT01 on the differentiation of osteoblasts under infected condition through determining the expression level of collagen Ⅰ (Col Ⅰ )mRNA in MG63 cells treated with Porphyromonas gingivalis (Pg).Methods:The cultured MG63 cells were divided into blank control,MT01,Pg, and MT01+Pg groups.MT01 at a concentration of 1 mg·L-1 was added into the MG63 cells,and the cells were incubated for 3 h.The cells treated with PBS (1 mg·L-1 )were used as control group.Then Pg (MOI=100∶1) was added.Real-time PCR was used to detect the expression levels of ColⅠ mRNA in MG63 cells at 2,4,6,8, 12 and 24 h after incubation.Results:Compared with blank control group,the levles of ColⅠ mRNA in the MG63 cells in MT01 and MT01 + Pg groups had no significant changes at 2 and 4 h (P > 0.05);the Col Ⅰ mRNA expression levels in MT01 group at 8,12 and 24 h were increased (P < 0.05 or P < 0.01).Compared with Pg group,the expression levels of ColⅠ mRNA in MT01+ Pg at 2 and 4 h were decreased,but the expression levels of ColⅠ mRNA were increased at 6,8,12 and 24 h (P <0.05 or P <0.01).Conclusion:MT01 can up-regulate the expression level of Col Ⅰ mRNA in the infected MG63 cells; MT01 could promot the differentiation of osteoblasts under infected condition.

Objective To discuss the application effect of peer support education in improving theself-management ability of old patients with diabetes. Methods A total of 160 cases of old patients with type 2 diabetes who were treated and hospitalized from June 2014 to August 2015 were selected, then equally divided into observation group and control group through using random number method.Finally, 76 cases were studiedin observation group, while 75 cases in control group. The health education guidance of conventional diabetes had been used in two groups for six months, and the peer support education was also conducted for the patients in observation group on the basis of conventional education. The self-management ability, insulin standard injection knowledge-belief and attitude-behavior/practice (KAP) and glycosylated hemoglobin (HbA1c) value of old patients with diabetes were observed before intervention, 3 months and 6 months later, respectively. Also,the hypoglycemia frequency in two groups was compared during intervention. Results After three months of intervention, the score of diet, exercise management, glucose monitoring, foot care, pharmaceutical administration and smoke for self-management ability in observation group was 4.63 ± 0.92, 4.18 ± 0.97, 2.86 ± 0.96, 2.35 ± 0.59, 4.01 ± 1.43 and 0.62 ± 0.29, respectively, while that of these indicators in control group was 3.69 ± 0.83, 3.52 ± 0.67, 1.75 ± 0.67, 1.63 ± 0.72, 3.05 ± 1.39 and 0.59 ± 0.38. Except smoke (P > 0.05), the differences between two groups were statistically significant (t=2.987-5.965, P < 0.05). After six months of intervention, the score of diet, exercise management, glucose monitoring, foot care, pharmaceutical administration and smoke for self-management ability in observation group was 5.86±0.93, 5.37±0.61, 3.97±0.94, 5.06±0.92, 5.81±0.73 and 0.89 ± 0.31, respectively, while that of these indicators in control group was 3.68 ± 0.96, 3.65 ± 0.95, 1.86 ± 0.88, 2.65±0.88, 3.21±1.13 and 0.81±0.39. The difference was statistically significant (t=9.336-15.633, P<0.01), except smoke (P>0.05). Then, the insulin was normally injected in observation group after six months of intervention, the score of knowledge, attitude and behavior was 5.63 ± 1.87, 43.17 ± 6.03 and 16.57 ± 1.59, while that in control group was 3.76 ± 0.83, 23.71 ± 0.59 and 10.16 ± 0.95. The differences between two groups were statistically significant (t= 8.569, 15.623, 6.751, P<0.01). Also, the level of glycosylated hemoglobin was decreased from (8.17 ± 0.32) % to (7.16 ± 0.41) %, and the difference was statistically significant (t=-3.560, P=0.000). Conclusions Peer support education couldenhance the self-management consciousness of old patients with diabetes, standardize the insulin injection, improve the ability of self-management and improve glucose metabolism index so that it is worthy of being clinically popularized and applied.

Objective To observe the incidence of radiation pneumonitis (RP) in patients with non-small cell lung cancer (NSCLC) or esophageal carcinoma treated by three-dimensional conformal radiation therapy (3DCRT), and investigate the predictive value of low dose volume of the lung on RP.Methods From Mar 2005 to Aug 2008, 161 patients with locally advanced NSCLC or esophageal carcinoma received 3DCRT. Fifty-three patients with NSCLC received radiotherapy of 60 Gy/30 -34 fx and concurrent chemotherapy of navelbine plus cisplatin (NP). Among the 108 patients with esophageal carcinoma with prescription doses ranging from 58 Gy/29 fx to 70 Gy/35 fx, 46 and 62 received 3DCRT alone or 3DCRT with concurrent chemotherapy of calcium folinate, 5-Fu and cisplatin (LFP), respectively. Univariate and multivariate analysis and receiver operating characteristics (ROC) curves were performed to assess the correlated factors of RP. Results The follow-up rate was 100%. The rate of RP was 57. 8% (93/161) for all patients, 94% (50/53,including 1 with Grade 4 and 1 with Grade 5) for patients with NSCLC, and 39.8% (43/108, none with Grade 4 and 5) for patients with esophageal carcinoma. The correlative factors included the sex, volume of gross tumor volume (GTV), mean lung dose (MLD), V5, V10, V15, V20, V25 and V30 of normal lung according to Spearman correlative analysis. Univariate analysis showed that all the 9 factors could predict RP. Only V5 and the volume of GTV were found independently associated with Grade 2 or more RP in multivariate analysis. ROC analysis indicated that the cut-off point of the curve was 55% with the area under ROC curve of 0. 684 (P = 0. 000). For the patients with lung V5 ≥ 55% and < 55% ,43% (36/84) and 18% (14/77) developed RP of Grade 2 or more, respectively. Conclusions Dosimetric parameters including MLD, normal tissue complication probability, and V5-V30 could predict RP. V5 may be the most valuable predictor. When V5 exceeds 55%, the probability of RP of grade 2 or more may increase notably. Besides the limitation of MLD, V20 and V30, the volume of low dose region should be also limited to a lower range during treatment planning.

OBJECTIVEThis aimed to investigate the effect of specific sequence oligodeoxynucleotide MT01 on the biological properties of osteoblasts invaded by Porphyromonas gingivalis (P. gingivalis ) by evaluating proliferation, cell cycle, and apoptosis.

METHODSMG63 osteoblasts were recovered and incubated with MT01, CpG ODN, metronidazole (MNZ), and gentamicin (GEN) for 3 h. P. gingivalis (the multiplicity of infection was 100:1) was added subsequently and cocultured for another 24 and 48 h. Cells with PBS comprised the blank group, whereas cells with P. gingivalis comprised the negative controls. Six experimental groups were established: PBS group, P. gingivalis group, MT01+P. gingivalis group, CpG ODN+ P. gingivalis group, MNZ+P. gingivalis group, and GEN+P. gingivalis group. The proliferative ability was measured by methyl thiazolyl tetrazolium assay, and the percentages of apoptosis and cell cycle were examined by flow cytometry.

RESULTSCompared with the blank group, proliferation increased significantly in the MT01+P. gingivalis group (P < 0.05). The ratio of cells was lower at the G₁ phase and higher at the S phase in the MT01+P. gingivalis group compared with the results in the P. gingivalis group (P < 0.05). Early cell apoptosis in the MT01+P. gingivalis group was significantly lower than that in the P. gingivalis group (P < 0.05).

CONCLUSIONMT01 can promote the proliferation, reduce the ratio of the G₁phase, increase the ratio of the S phase, and inhibit the early apoptosis of osteoblasts invaded by P. gingivalis.
