Objective To investigate the relationship between the life quality and the disease uncertainty of the patients with high risk of diabetic foot. Methods The data of 235 patients with high risk of diabetic foot were selected by the convenience sampling method, using the life quality scale for patients with type 2 diabetes mellitus(DMQLS revised edition) and the uncertainty of disease scale (MUIS). Results The total score on life quality in the diabetic patients with high risk was (138.04 ± 7.32), which was at a high level. The psychological dimension ranked on the top in terms of the score, following by physiological dimension, social dimension, disease dimension and satisfaction dimension. The overall score on the uncertainty was (100.09 ±6.89), which was at intermediate level. The dimension of unpredictability ranked on the top, followed by uncertainty, complexity and lack of information. Pearson correlation analysis showed that the uncertainty together with its four dimension was negatively related with quality of life (all P <0.05). Conclusions The life quality in the patients with high risk of diabetes is generally poor and their sense of uncertainty is at the moderate level. The quality of life is negatively correlated with the uncertainty of disease. So reducing the disease uncertainty is helpful for the improvement of the quality of life.

Objective To study the effect of cold and heat treatment on metastasis and the peripheral blood immune response in patients with breast cancer. Methods A total of 124 breast cancer patients were randomly di-vided into a hot and cold therapy group and a control group, each of 62. Both groups were given conventional surgical resections, and the hot and cold therapy group was given cooling and heating physical therapy for one month before the operation. The efficacy of the treatment and the patients′ spiritual state were compared after the treatment. The effect on lung metastases was evaluated using tomographic images of the chest, and the changes in immune cell levels in the peripheral blood were detected using flow cytometry. Results After the treatment, the remission rate (54.8%), spiritual life ratings on the Karnofsky scale and the area of lung cancer nodule transfer were significantly better in the hot and cold therapy group than in the control group. Twelve weeks after the treatment, the percentage of MDSCs in the control group patients was 72.5%, significantly higher than the 5.3% of the therapy group. The CD4+and CD8+ T cells were 2.2% and 1.8%, significantly lower than the 26.7% and 13.9% of the control group. Con-clusion Cold and hot therapy before a mastectomy can effectively inhibit the metastasis of breast cancer and promote patients′physical rehabilitation and spiritual life. It may regulate the microenvironment of their immunosuppression and stimulate antitumor immunity.

This study was aimed to establish an analysis method of amentotaxus biflavone distribution in rats' tissues, including the heart, liver, spleen, lungs, kidney, brain, stomach, large intestine and small intestine, in order to investigate its distribution characteristics in tissues after rats gavaged with amentotaxus biflavone. HPLC-UV was employed to determine contents of amentotaxus biflavone in rats' tissues. The intragastric administration dose of amentotaxus biflavone was 500 mg·kg-1. Rats were sacrificed by cervical dislocation 10 min, 0.5, 1, 2, 4, 8, 12 h after intragastric administration. Tissues of the heart, liver, spleen, lungs, kidney, stomach, large intestine, small intestine and brain were removed and dissected immediately. Distribution of amentotaxus biflavone in each tissue was determined after processing. The results showed that tissue in different range had a good linear range. The lowest detection limit was 0.125 ng. The RSD of intra and inter-day was less than 10%. The absolute recovery rate of amentotaxus biflavone in each tissue was between 75.07% and 89.80%. The relative recovery rate was between 92.00% and 107.00%. Amentotaxus biflavone in each tissue was stable in different tissues in refrigerator of -20° C for 15 days. It was concluded that there were relatively large concentration differences of amentotaxus biflavone in different tissues. After intragastric administration, amentotaxus biflavone was mainly distributed in the stomach, large intestine, small intestine, liver and kidney, and then the heart, lungs and spleen. It also distributed in brain tissues through the blood-brain barrier.

Objective To explore the prevalence of anxiety and depression among the medical staff of a children's hospital, and to understand their relationship with age, gender, educational background, family income, family harmony, position, marital status, experience, title, work pressure, weekly working hours, chronic diseases and stressful events.Methods The medical staff of a children's hospital were evaluated using Zung's self-rating anxiety scale (SAS) and self-rating depression scale (SDS).The scores were correlated with age, gender, educational background, family income, family harmony, position, marriage, working years, title, work pressure, weekly working hours, chronic diseases, and stressful events data collected about the same respondents.Results There were 320 respondents suffering from anxiety disorders and 392 experiencing depression among the 677 medical staff surveyed.There were 288 who suffered from anxiety associated with depression.There was a significant difference between the males and the females.Marital status, family harmony, chronic disease and stress events were all significant predictors of anxiety or depression.A univariate analysis showed that neither education nor family income had significant predictive power, but age, professional title,working years, working pressure and working in different departments were all significant predictors.Medical staff with different weekly working hours showed significantly different average levels of anxiety, but position had no such effect.Position was, though, significantly correlated with depression score, while weekly working hours were not.Multivariable logistic regression models showed that educational background, working pressure, family harmony, chronic disease and stressful events were all significant predictors of anxiety.Working pressure, family harmony and chronic disease were related to depression.Conclusion Significant anxiety and depression were observed among the medical staff of this children's hospital.Working pressure, family harmony and chronic disease are strong predictors of anxiety and depression.

Objective To study the feasibility and safety of interventional closure for the treatment of infant’s perimembranous ventricle septal defect (PmVSD). Methods During the period from Jan. 2012 to Jan. 2013, a total of 229 single PmVSD infants less than three years of age were admitted to authors ’ hospital. The infantile patients were divided into intervention group (n = 88) and surgery group (n = 141). Patients in the intervention group underwent interventional closure procedure , while patients in the surgery group received conventional cardiac surgery. The operation success rate , the main and minor complication rates, the operation time, the postoperative hospitalization days, the incidence of postoperative pulmonary infection and the medical cost were recorded , and the results were compared between the two groups. Results No statistically significant differences in the operation success rate, the main complication rate, the postoperative hospitalization days and the medical cost existed between the two groups (P > 0.05). But the minor complication rate and the operation time of the intervention group were better than those of the surgery group. In the surgery group, the minor complication was mainly the respiratory infection, which was manifested as higher leukocyte count, higher C-reactive protein level, higher myocardial damage marker level as well as higher vasoactive drug scores in 24 hours after the operation , and the above items were significantly higher than those in the intervention group. Conclusion For the treatment of infant’s perimembranous ventricle septal defect, percutaneous transcatheter closure is clinically feasible. This technique is safe and reliable with obvious advantages when the indication is strictly observed and the procedure is carefully manipulated. This treatment can partly replace the conventional surgery.
