With the gradual deepening of the reform in the medical and health system, reform and innovation inside hospitals have come to carry increasingly great weight. In light of their hospital's practical experience and proceeding from factors that affect innovation, the process of innovation and the links of innovation, the authors put forward ways for hospital innovation and the principles that ought to be adhered to. They argue that in striving for innovation, hospitals should first of all give priority to the building of the contingents of department heads and young and middle aged key professional and technological members, set forth an advanced operating strategy and goal, highlight innovation through science and technology, and create a sound environment for innovation. On the basis of establishing an effective mechanism for innovation, hospitals ought to stick to the principles of humanistic management, close attention to the actual conditions and objective evaluation.

Objective To study the expressions of apoptotic protease activating factor-1(Apaf-1)and astrocyte elevated gene-1(AEG-1)in colonic carcinoma,and to explore their correlations with the clinical path-ological features. Methods The expressions of Apaf-1 and AEG-1 were detected in 63 colonic carcinoma sam-ples and 30 normal colonic mucosa adjacent to tumor nest by immunohistochemical method,and their correla-tions with clinical features of colonic carcinoma were analyzed. Results The positive expressions of Apaf-1 and AEG-1 in colonic carcinoma were 23. 81%(15 / 63)and 68. 25%(43 / 63),respectively. The positive expre-ssions of Apaf-1 and AEG-1 in normal colonic mucosa were 76. 67%(23 / 30)and 26. 67%(8 / 30),respec-tively. The positive expression rate of AEG-1 was significantly higher in colonic carcinoma than that in normal tissue(χ2 = 14. 192,P = 0. 000). However,the expression of Apaf-1 was signi-ficantly lower in colonic carci-noma than that in normal tissue(χ2 = 23. 497,P = 0. 000). The expression of Apaf-1 was negatively correlated to the expression of AEG-1(r = - 0. 339,P = 0. 007). The expressions of AEG-1 and Apaf-1 were associated with differentiation degree(χ2 = 4. 643,P = 0. 031;χ2 = 12. 034,P = 0. 001)and clinical stage(χ2 = 6. 628, P = 0. 010;χ2 = 8. 246,P = 0. 004),but they were not correlated with age(χ2 = 1. 462,P = 0. 227;χ2 =2. 401,P = 0. 121)and tumor size(χ2 = 0. 333,P = 0. 564;χ2 = 0. 590,P = 0. 442). Conclusion The expression of AEG-1 is up-regulated in colonic carcinoma,but the expression of Apaf-1 is down-regulated,with a significant negative correlation. Apaf-1 and AEG-1 may be closely related to the occurrence and development of colon carcinoma. Therefore,combination detection of Apaf-1 and AEG-1 may be more valuable for the prog-nosis evaluation of colonic carcinoma.

OBJECTIVETo compare iron bioavailability (Fe BV) from ten selected kinds of Chinese wheat flours in order to provide scientific basis for further human trials and enable plant breeding programs to screen biofortified wheat cultivars.
METHODSAn in vitro digestion/Caco-2 cell model was used to assess Fe BV of ten flour samples from six leading Chinese wheat cultivars and the stability of Fe BV in one cultivar was studied across three growing environments.
RESULTSSignificant differences were observed in both Fe BV and Fe bioavailability per gram of food (Fe BVPG) among cultivars (P<0.01) grown at the same location with the same flour extraction rate. Zhongyou 9507 and Jingdong 8 had Fe BV 37%-54% and Fe BVPG 103%-154% higher than the reference control. In the Anyang environment, Zhongyou 9507 had a higher wheat flour-Fe level and Fe BVPG. Differences in Fe BV were detected in cultivars with different flour extraction rates.
CONCLUSIONZhongyou 9507 and Jingdong 8 were identified as the most promising cultivars for further evaluation of efficacy by using human subjects. The growing environments had no effect on Fe BV, but did have a significant effect on Fe BVPG. Fe bioavailabilities in low-extraction (40%) flours were higher than those in high-extraction (78%) flours.

Objective:
To explore effects of perforator flaps combined with muscle flaps for repairing grade Ⅳ pressure ulcers in ischial tuberosity of elderly patients.
Methods:
Nine elderly patients with grade Ⅳ pressure ulcers in ischial tuberosity were hospitalized in our burn ward from April 2014 to April 2017. Size of wounds ranged from 5 cm×3 cm to 12 cm×7 cm, and depth of sinus ranged from 6 to 22 cm. After admission, emergency debridement or debridement in selective time was performed. After debridement, the wounds were treated with continuous vacuum assisted closure therapy. After the treatment for 1 to 2 weeks, tissue flaps repair operations were performed. Four patients were repaired with inferior gluteal artery perforator flaps combined with long head of biceps femoris muscle flaps. Three patients were repaired with inferior gluteal artery perforator flaps combined with semimembranous muscle flaps. One patient was repaired with inferior gluteal artery perforator flap combined with gracilis muscle flap. One patient was repaired with femoral profound artery perforator flap combined with gluteus maximus muscle flap, and the distal area of femoral profound artery perforator flap of the patient which showed intraoperative cyanosis of 6 cm×4 cm was thinned to medium thickness skin to cover the muscle flap. The other eight patients showed no abnormality during operation. Size of perforator flaps ranged from 7 cm×5 cm to 14 cm×12 cm, and size of muscle flaps ranged from 11 cm×4 cm to 24 cm×6 cm. The donor sites of flaps were all sutured directly.
Results:
The tissue flaps and skin graft of all patients survived well after operation. During follow-up of 8 to 35 weeks, operative area of all patients showed good shape and texture, with no local diabrosis or recurrence of pressure ulcers.
Conclusions
The combination of perforator flaps and muscle flaps is effective in repairing and reducing recurrence of grade Ⅳ pressure ulcers in ischial tuberosity of elderly patients.

Single-cell RNA sequencing (scRNA-seq) is used for transcriptome profiling at the individual cell level, which is capable of screening in differentially gene expression that results from genetic mutation. Islet-based developmental atlas and heterogeneity characterization are currently the main applications of scRNA-seq in diabetes. scRNA-seq also can be used to mark and purify the functional β cells from resident adult stem cells in the pancreatic islets, which is expected to improve the outcome of islet β cells transplantation in type 1 diabetic patients. In addition, the technique can aid in learning diabetic β cell dedifferentiation and immunomodulatory functions. Although the study of scRNA-seq in diabetic retinopathy, nephropathy, atherosclerosis, and peripheral neuropathy is still at a nascent stage, scRNA-seq has great potential in a wide range of biomedical and clinical applications.

OBJECTIVETo retrospectively analyze the risk factors and clinical manifestations of myocardial damage of patients with severe burn in order to provide evidence for its prevention and treatment.
METHODSTwo hundred and fifty-two patients with severe burn admitted to 5 burn centers from January 2010 to June 2015, conforming to the study criteria, were treated in accordance with the fluid resuscitation formula of the Third Military Medical University. According to the creatine kinase isoenzyme-MB (CK-MB) level before treatment on admission, patients were divided into non-myocardial damage group (n=118, CK-MB level less than 75 U/mL) and myocardial damage group (n=134, CK-MB level higher than or equal to 75 U/mL). Data of patients in two groups were collected and evaluated such as gender, age, body mass, number of patients with chemical burn, admission time after injury, total burn area, full-thickness burn area, number of patients with inhalation injury, levels of haemoglobin, hematocrit, and blood lactate on admission and at post injury hour (PIH) 24 and 48, volumes of urine output and fluid input at PIH 24 and 48, levels of creatinine, urea nitrogen, total bile acid, diamine oxidase on admission and at PIH 24 and 48, and mortality. Furthermore, patients were divided into three groups, i. e. less than 50% total body surface area (TBSA) group (n=110), larger than or equal to 50% TBSA and less than 80% TBSA group (n=83), and larger than or equal to 80% TBSA group (n=59) according to the total burn area, and the incidence rates of myocardial damage in patients of three groups were recorded. Data were processed with chi-square test, t test, Wilcoxon test, analysis of variance for repeated measurement, and the values of P were adjusted by Bonferroni. Basic data of 252 patients were processed with binary logistic regression analysis. Receiver operating characteristic curve of total burn area of 252 patients was drawn to predict myocardial damage.
RESULTS(1) There were no statistically significant differences in age, body mass, number of patients with chemical burn, number of patients with inhalation injury, and full-thickness burn area between two groups (with t values respectively 0.20 and 0.31, χ(2) values respectively 0.49 and 4.10, Z=1.42, P values above 0.05). There were statistically significant differences in gender, admission time after injury, and total burn area of patients between two groups (χ(2)=5.00, with t values respectively 2.44 and 3.13, P<0.05 or P<0.01). (2) Gender, admission time after injury, and total burn area were independent risk factors related to myocardial damage in the patients (with odds ratios respectively 2.608, 3.620, and 1.030; 95% confidence intervals respectively 1.315-5.175, 1.916-6.839, and 1.011-1.049; P values below 0.01). (3) The incidence rates of myocardial damage of patients in less than 50% TBSA group, larger than or equal to 50% TBSA and less than 80% TBSA group, and larger than or equal to 80% TBSA group were 38.2% (42/110), 54.2% (45/83), and 61.0% (36/59) respectively, and there was statistically significant difference among them (χ(2)=9.46, P<0.05). (4) The total area under receiver operating characteristic curve of total burn area to predict myocardial damage of 252 patients was 0.706 (with 95% confidence interval 0.641-0.772, P<0.01), and 51.5% TBSA was chosen as the optimal threshold value, with sensitivity of 62.6% and specificity of 65.3%. (5) Compared with those in non-myocardial damage group, except the levels of haemoglobin and hematocrit at PIH 48 (with t values respectively -0.76 and -0.61, P values above 0.05), the levels of haemoglobin, hematocrit, and blood lactate of patients in myocardial damage group were significantly increased at each time point (with t values from -2.80 to -2.06, P<0.05 or P<0.01). Compared with those in non-myocardial damage group, the volume of urine output of patients was significantly declined (with t values respectively 2.05 and 3.68, P<0.05 or P<0.01), while the volume of fluid input of patients was not obviously changed in myocardial damage group at PIH 24 and 48 (with t values respectively 1.01 and 1.08, P values above 0.05). (6) Compared with those in non-myocardial damage group, the level of creatinine of patients was significantly increased on admission and at PIH 24 and 48 (with Z values from -2.91 to -1.99, P<0.05 or P<0.01), the level of urea nitrogen of patients was only significantly increased at PIH 24 and 48 (with t values respectively -4.75 and -5.24, P values below 0.01), the level of total bile acid of patients was not obviously changed on admission and at PIH 24 and 48 (with t values from -0.81 to -0.20, P values above 0.05), and the level of diamine oxidase of patients was only significantly increased on admission and PIH 24 in myocardial damage group (with t values respectively -3.97 and -2.02, P<0.05 or P<0.01). (7) Compared with that in myocardial damage group, the mortality of patients in non-myocardial damage group was significantly declined (χ(2)=5.81, P<0.05).
CONCLUSIONSPatients with severe burn have high incidence of myocardial damage, which may be predicted by total burn area. Severely burned patients with myocardial damage are more likely to suffer from decline of effective circulating volume, tissue oxygenation disorders, and damage in other organs in shock stage.

Objective:To analysis the correlation of eating speed with obesity.Methods:A total of 644 people aged 40-65 from Caihe Community in Hangzhou were enrolled to collect clinical and demographic data, undergo extensive physical examination and laboratory tests. Participants were divided into two groups according to their eating speed (non-fast and fast). Obesity-related parameters were compared between two groups. Multivariable logistic regression was conducted to explore the relationship between eating speed and obesity after adjusting confounders.Results:Body mass index, waist circumference, and visceral fat area were greater in the fast eating group than non-fast eating group(all P<0.01). After adjusting for age, gender, smoking, alcohol drinking, physical activity level per week, and principal food intake, logistic regression analysis showed that eating fast was correlated with abdominal obesity( OR=1.66, 95% CI 1.11-2.48, P=0.014) and visceral obesity( OR=1.65, 95% CI 1.14-2.39, P=0.007). After stratified by gender, in the group of men, eating fast was correlated with abdominal obesity( OR=2.04, 95% CI 1.07-4.04, P=0.032) and visceral obesity( OR=1.85, 95% CI 1.04-3.31, P=0.037); In the group of women, eating fast was correlated with overweight and obesity( OR=1.59, 95% CI 1.04-2.42, P=0.031). Conclusion:Eating fast is positively associated with obesity. Interventions for reducing eating speed may be effective for weight control.

Objective:To investigate the risk factors of diabetic nephropathy (DN) in primary type 2 diabetes mellitus (T2DM) patients and to quantitatively analyze the risk of DN by nomogram modeling.Methods:A total of 1 588 primary T2DM patients from 17 townships and streets in Zhejiang Province were enrolled from June 2018 to August 2018 in this cross-sectional study, with an average age of (56.8±10.1) years (50.06% male) and a mean disease duration of 9 years. The clinical data, biochemical test results, and fundus photographs of all T2DM patients were collected, and logistic regression analysis was used to screen the risk factors of DN. Then, a nomogram model was used to quantitatively analyze the risk of DN.Results:DN occurred in 27.71% (440/1 588 cases) primary type 2 diabetes patients. Hemoglobin A 1c (HbA 1c) ( OR=1.159, 95% CI 1.039-1.292), systolic blood pressure ( OR=1.041, 95% CI 1.031-1.051), serum creatinine (Scr) ( OR=1.011, 95% CI 1.004-1.017), serum globulin (GLOB) ( OR=1.072, 95% CI 1.039-1.105), diabetic retinopathy (DR) ( OR=1.463, 95% CI 1.073-1.996), education level of more than junior high school ( OR=2.018, 95% CI 1.466-2.777), and moderate-intensity exercise ( OR=0.751, 95% CI 0.586-0.961) were influencing factors of DN. Nomogram model analysis showed that the total score of each factor of DN ranged from 64-138 points, and the corresponding risk rate ranged from 0.1-0.9. The nomogram model also predicted a C-index value of 0.753 (95% CI 0.726-0.781) and an area under the receiver operating characteristic curve of DN of 0.753. Internal verification of the C-index reached 0.738. The model displayed medium predictive power and could be applied in clinical practice. Conclusions:HbA 1c, systolic blood pressure, Scr, GLOB, DR, and more than a junior high school education are independent risk factors of DN. Nomogram modeling can more intuitively evaluate the risk of DN in primary T2DM patients.
