Diabetes is a chronic noncommunicable disease,which is can't be cured,and only can be suppressed by long-term treatment and self-management.The clinical decision support system can simulate the thinking process of diabetes specialists in disease diagnosis,and can provide the regular medical treatment plans and recommend the optimal plans to doctors.Most of the existing clinical decision support systems are based on clinical guidelines,rule-based and case-based reasoning as well as ontology-based systems.The big data technology can acquire and process multiple heterogeneous data,and provide a more scientific personalized treatment plan.In recent years,a variety of big date processing methods have been applied to the clinical diagnosis of diabetes based on decision tree,neural network,fuzzy logic,support vector machine,APRIORI association rules and multidimensional analysis,and timing mining.However,these methods are still in preliminary stage.The framework of diabetes clinical decision support system based on big data technology was analyzed,and the future diagnostic and treatment methods were forecast.

Objective To describe the adequate feeding of early enteral nutrition in critical patients with cancer, and explore its influencing factors. Methods A retrospective analysis study was performed and 161 patients were involved. Results Nearly 57.14%patients got adequate feeding. The independent risk factors included complications (P < 0.05,OR=2.312,OR 95%CI 1.078-4.958), Acute Physiology and Chronic Health Evaluation Ⅱ (APACHEⅡ) scores (P < 0.05,OR=1.111,OR 95%CI 1.017-1.214) and hypoalbuminemia (P<0.05,OR=2.252,OR 95%CI 1.036-4.892) , and the protective factor was previous enteral nutrition experience (P<0.01,OR=0.123,OR 95%CI 0.021-0.494). Patients who got adequate feeding showed more increase in albumin levels, more decrease in APACHEⅡscores and shorter ICU stays. Conclusions Part of patients got inadequate feeding, due to comprehensive effects of many factors. And adequate feeding may be beneficial to the increase of albumin levels, also helps patients rehabilitate early and shorten the ICU stays.

Objective:To investigate whether idebenone can improve behavioral disorders in mice with Parkinson disease (PD) by increasing PHB2 mediated mitophagy.Methods:In the first small experiment, thirty mice were randomly divided into normal control group, model group and treatment group according to the random number table method, with 10 animals in each group.The aim of this study was to observe the effect of idebenone on the behavior of Parkinson disease model mice. In the second experiment, 20 mice were randomly divided into blank control group, MPTP group, shRNA-PHB2 group and shRNA-PHB2+ MPTP group, with 5 mice in each group. The changes of tyrosine dehydrogenase (TH) in brain tissue were detected by immunofluorescence assay. In the third experiment, 30 mice were randomly divided into blank control group, shRNA-PHB2 group, MPTP+ idebenone group, shRNA-PHB2+ MPTP group, shRNA-PHB2+ idebenone group and shRNA-PHB2+ MPTP+ idebenone group, with 5 animals in each group. The aim of this study was to investigate the effect of idebenone on mitochondrial autophagy in mouse brain.C57BL-6 mice were intraperitoneally injected with MPTP to establish the animal model of chronic PD. Then 200 mg / kg idebenone was given by gavage for 21 days. And the expression of PHB2 in brain was inhibited by microinjection of adeno-associated virus 9 (AAV9) shRNA inhibin 2(PHB2) into lateral ventricle. The behavioral changes of the PD mice were detected by Morris water maze, and the changes of tyrosine dehydrogenase (TH) induced by inhibiting PHB2 were detected by immunohistochemistry. The protein expression of LC3 and PHB2 in substantia nigra of midbrain was detected by Western blot.The data were analyzed by GraphPad 7.0 and SPSS 22.0.Results:(1) In the water maze test data of the first small experiment, the repeated measurement ANOVA showed that the group-time interaction effects of latency of mice from 1 to 7 days were significant ( Ftime×group=20.51, P<0.05). Simple effect analysis showed that on the 5th, 6th and 7th day, the incubation period of the treatment group was significantly shortened (all P<0.05). Univariate analysis of variance showed that on the 7th day of the test, the differences between the control group and the model group, the model group and the treatment group, the control group and the treatment group were all statistically significant( t=-49.95, -21.81, 28.14; all P<0.01). In the third small experiment, repeated measurement analysis of variance showed that the interaction between time and group was significant ( Ftime×group=42.11, P<0.01). Simple effect analysis showed that compared with MPTP+ idebenone group, the latency of shRNA-PHB2+ MPTP+ idebenone group was significantly prolonged (all P<0.05). There were no significant difference between shRNA-PHB2+ MPTP+ idebenone group and shRNA-PHB2+ MPTP group except the 4th day ( P<0.05). On the 7th day, compared with MPTP+ idebenone group, the residence time of shRNA-PHB2+ MPTP+ idebenone group was significantly increased ( t=-34.36, P<0.001), but there was no significant difference between shRNA-PHB2+ MPTP group and shRNA-PHB2+ MPTP+ idebenone group ( t=2.94, P>0.05). (2)The results of immunofluorescence experiment showed that the relative expression of TH in the control group, model group, shRNA-PHB2 group and shRNA-PHB2+ MPTP group were (41.03±3.01), (24.20±4.18), (38.39±3.31) and (13.12±2.65), respectively. Compared with the control group, the expression of TH in the midbrain of the MPTP group was significantly down-regulated, the difference was statistically significant( t=7.98, P<0.01). Compared with the MPTP group, the expression of TH in shRNA-PHB2 group was down regulated ( t=-6.73, P<0.05). (3) Western blot results showed that the relative expression of LC3 in midbrain tissue of control group, shRNA-PHB2 group, MPTP+ idebenone group, shRNA-PHB2+ MPTP group, shRNA-PHB2+ idebenone group and shRNA-PHB2+ MPTP+ idebenone group were (0.86±0.07), (0.77±0.08), (0.42±0.05), (0.21±0.05), (0.66±0.09) and (0.27±0.07). The relative expression of PHB2 were (1.13±0.14), (0.56±0.11), (1.08±0.14), (0.27±0.07), (0.68±0.14) and (0.24±0.10). Compared with MPTP+ idebenone group, the relative expression of LC3 and PHB2 in shRNA-PHB2+ MPTP+ idebenone group was significantly decreased ( F=1.96, P<0.01). Conclusion:Idebenone can increase the level of mitophagy in PD mice through PHB2, thus improving the behavioral disorder.

OBJECTIVE: To study whether the effects of olanzapine on gastrointestinal motility is related to the serotonin antagonism and myosin light chain kinase. METHODS: Male Sprague-Dawley rats were randomly divided into four groups. Olanzapine gavage was performed for each treatment group during the course of 30 continuous days, while the same volume of saline was given to the rats in the control group. Defecation of the rats was observed on days 7 and 30 after olanzapine gavage. The effects of olanzapine on contraction of colonic smooth muscles were observed in ex vivo experiments. A Western blot was used to evaluate expression levels of the serotonin transporter (SERT) and MLCK in colon segments of the rats. RESULTS: ResultsaaCompared to the control group, 5-160 µM of olanzapine could inhibit dose-dependently the contraction of colonic smooth muscle ex vivo experiments. The maximum smooth muscle contraction effects of 5-HT and acetylcholine significantly decreased after treatment with 40-160 µM of olanzapine. Constipation was found in the olanzapine-treated rats on day 7 and have sustained day 30 after gavage. Expression of MLCK in olanzapine-treated rats was significantly decreased, whereas the expression of SERT significantly increased on the day 7, then significantly decreased on the day 30 after olanzapine gavage. CONCLUSION: SERT and MLCK may involve in the inhibition of colonic contraction induced by olanzapine.

Objective: To learn the status and influencing factors of development among infants at ages of 0 to 36 months in Xiaoshan District, Hangzhou City, so as to provide the reference for promoting healthy development of infants. Methods: Infants at ages of 0-36 months who underwent physical examination in Child Health Clinic of Xiaoshan District Community Health Service Center were selected in 2022. General data of infants and their mothers were collected through questionnaires, and the development status of infants was screened by Age and Stages Questionnaire (third edition). Factors affecting the development status were identified using a multivariable logistic regression model. Results: A total of 2 519 infants were investigated, including 1 339 males (53.16%) and 1 180 females (46.84%). There were 608 infants with abnormal development of at least one functional area of communication (CM), gross motor (GM), fine motor (FM), problems solving (CG) and personal-social (PS). The abnormal rate was 24.14%, and the abnormal rates of the above functional areas were 9.77%, 6.59%, 7.98%, 6.39% and 9.33%, respectively. Multivariable logistic regression analysis showed that gender (male, OR=1.563, 95%CI: 1.191-2.052), mother's childbearing age (≥35 years, OR=1.411, 95%CI: 1.001-1.988), mother's educational level (lower than junior college, OR=1.460, 95%CI: 1.116-1.912) were factors affecting abnormal development of CM; preterm birth (OR=2.323, 95%CI: 1.315-4.103) was factors affecting abnormal development of GM; gender (male, OR=1.654, 95%CI: 1.225-2.232) was factors affecting abnormal development of FM; gender (male, OR=1.511, 95%CI: 1.086-2.102) and mode of delivery (cesarean section, OR=1.460, 95%CI: 1.060-2.010) were factors affecting abnormal development of CG; gender (male, OR=1.340, 95%CI: 1.019-1.763) and birth weight (low birth weight, OR=1.985, 95%CI: 1.149-3.432) were factors affecting abnormal development of PS. Conclusions The rate of abnormal development among infants at ages of 0 to 36 months in Xiaoshan District is 24.14%. Gender, preterm birth, mode of delivery, birth weight, mother's childbearing age and mother's educational level could affect the development status of infants.

ObjectiveTo investigate the efficacy of haploidentical blood and marrow transplantation (haplo-BMT) in the treatment of advanced chronic myeloid leukemia (CML).MethodsFrom November 2002 to October 2007,35 patients with advanced CML received haplo-BMT.Eleven patients achieved the second chronic phase (CP2) after treatment with imatinib or chemotherapy or both before pre-conditioning,but there were 13 cases in accelerated phase (AP) and 11 patients in blast phase (BP) at the time of transplantation.By the last follow-up date October 31,2011,the median follow-up time among living patients was 67 months (range,49 to 100 months).ResultsThe cases of HLA-antigen mismatched between donors and recipients as 1,2,and 3 antigens were 1,12,and 22 respectively.The number of mean mononuclear cells and CD34+ cells was (7.19+ 1.37) × 108/kg and (2.54± 1.50) × 106/kg,respectively.All but one patient achieved durable hematopoietic reconstitution. Hyperacute graft-versus-host disease (GVHD) occurred in 28.6％ (10/35) patients.The cumulative incidence of grade Ⅱ to Ⅳ acute GVHD was 48％.Among 27 patients who survived longer than 100 days after transplant,16 (60 ％) had chronic GVHD.Fiveyear overall survival (OS) rate was 46.2％ and 45.5％ in CML-AP and BP (P =0.97),respectively.Five-year probability of OS rate was 81.8％,30.8％ and 27.3％ in patients with CML-CP2,CML-AP and BP at transplant,respectively.The OS of CML-CP2 was significantly higher than CML-AP and BP at transplant (P＜0.01 ).ConclusionHaplo-BMT is a feasible therapeutic mean for patients with advanced CML who have no matched donors available.It is better to perform haplo-BMT at CML-CP2 other than CML-AP or BP.

Objective:To investigate the effects of early sleep deprivation(SD) on depressive-like behavior and hippocampus synaptic plasticity in adult mice with chronic unpredictable mild stress(CUMS) model.Methods:Thirty 2-week-old clean grade male mice were randomly divided into control group (CON group), CUMS group and SD + CUMS group according to the random number table, with 10 mice in each group. The mice in SD + CUMS group were subjected with sleep deprivation for 4 hours once a day during puberty (3 ~ 6 weeks old), and then were stimulated by CUMS after adulthood (9 weeks old). The mice in CUMS group were subjected with CUMS at the age of 9 weeks. And the mice in CON group were not given any intervention.The depressive-like behavior was evaluated by body weight, sugar water preference, tail suspension test and forced swimming test.The density of dendritic spines of basal and apical neurons in hippocampal CA1 was measured by Golgi staining, the frequency and amplitude of miniature excitatory postsynaptic current(mEPSC) of pyramidal neurons in the hippocampal CA1 region of mice were measured by electro-physiological patch clamp technique.Graphpad prism 7.0 software was used for statistical analysis and mapping. One-way ANOVA was used for comparison among multiple groups, and Tukey test was used for further pairwise comparison.Results:(1) After stress modeling, there were significant differences in body weight, sugar water preference percentage, forced swimming immobility time and tail suspension time among the three groups ( F=71.63, 39.82, 44.13, 43.07, all P<0.01). Compared with CON group, the mice in CUMS group and SD+ CUMS group had lower body weight ((25.51±0.37) g, (22.92±0.31) g, (20.12±0.27) g, both P<0.01), lower sugar water percentage preference ((87.40±1.65) %, (63.42±3.33) %, (49.68±3.70)%, both P<0.01), longer immobile time of forced swimming ((34.30±5.32) s, (119.20±12.03) s, (153.80±9.17) s, both P<0.01) and longer immobile time of tail suspension test((115.20±8.19)s, (156.80±4.35) s, (192.00±4.12) s, both P<0.01). Compared with CUMS group, SD+ CUMS group had lower body weight ( P<0.01), lower sugar water preference percentage ( P<0.05), longer immobile time in forced swimming test( P<0.05) and longer immobile time in tail suspension test( P<0.01). (2) Golgi staining results showed that the densities of dendritic spines of apical neurons and basal neurons in hippocampal CA1 area of the three groups were significantly different ( F=38.41, 41.34, both P<0.01). The densities of dendritic spines of basal and apical hippocampal neurons in CUMS group and SD+ CUMS group were lower than those in CON group ((7.74±0.22)/10 μm, (6.58±0.27)/10 μm, (5.00±0.13)/10 μm, both P<0.01), ((8.90±0.23)/10 μm, (7.63±0.30)/10 μm, (6.01±0.14)/10 μm, both P<0.01). Compared with CUMS group, the mice in SD+ CUMS group had lower densities of dendritic spines of basal and apical hippocampal neurons(both P<0.01). (3) Electrophysiological results showed that there were significant differences in the frequency and amplitude of mEPSC in hippocampal pyramidal neurons of the three groups ( F=38.90, 63.37, both P<0.01). Compared with CON group, the frequency and amplitude of mEPSC in pyramidal neurons of CA1 in CUMS group and SD+ CUMS group were significantly lower ((0.39±0.03)Hz, (0.20±0.02)Hz, (0.07±0.02)Hz, both P<0.01; (9.98±0.31)pA, (7.74±0.21)pA, 6.36±0.13)pA, both P<0.01). Compared with CUMS group, the frequency and amplitude of mEPSC in SD+ CUMS group were lower (both P<0.01). Conclusion:Adolescent sleep deprivation aggravates depressive behavior and hippocampus synaptic plasticity impairment in adult CUMS model mice.

OBJECTIVETo evaluate the efficacy of HLA- haploidentical donor hematopoietic transplantation (Haplo- HSCT)for severe aplastic anemia (SAA)by compared with the same period of unrelated donor transplantation (UD- HSCT).

METHODSOf a cohort of 50 SAA patients between September 2012 and July 2014, 26 patients underwent UD- HSCT and 24 patients Haplo- HSCT.

RESULTSOS rate was 91.3% with a median follow-up of 9 (2-26)months. According to transplant type, there was no significant difference between UD- and Haplo-HSCT (96.1%vs 86.0%,P=0.30). 3 of 50 (6%)patients had primary engraft failure. Haplo- HSCT developed higher significantly incidence of Ⅱ- Ⅳ aGVHD (37.5%vs 3.83%,P=0.003)and cGVHD (37.5%vs 15.3%,P=0.030)than UD-HSCT. Haplo-HSCT also had significantly higher incidences of CMV viremia (78.2%vs 46.1%,P=0.005)and EBV viremia (43.1%vs 16.0%,P=0.040), respectively than UD-HSCT. But the incidences of hemorrhagic cystitis were similar between two transplant types (39.1%vs 23.0%,P=0.120).

CONCLUSIONThis study showed favorable outcome of Haplo-HSCT for SAA, which was comparable with UD-HSCT.

Objective: To investigate the effect of minimal residual disease (MRD) monitoring by multiparameter flow cytometry (MFC) pre-conditioning on prognosis of acute myeloid leukemia in first complete remission (CR₁-AML) after allogeneic hematopoietic stem cell transplantation (allo-HSCT) , and to explore the value of MRD monitoring by MFC in the prognosis evaluation on allo-HSCT in CR₁-AML. Methods: Between April 2012 and March 2015, consecutive 186 patients with CR₁-AML who underwent allo-HSCT were analyzed retrospectively. MRD in BM before conditioning was detected by eight-color MFC. Any level of residual disease was considered to be MRD positive. Results: ①Of 186 patients, MRD was negative in 151 patients, positive in 35 patients (<1% in 25 patients and 1% to 3% in 10 patients) . ② With the median follow up of 18 (5-41) months, two-year DFS was 80.0% (95%CI 68.5%-92.3%) . Univariate analysis showed that MRD positive patients had lower DFS[62.9% (95%CI 50.6%-75.2%) vs 88.9% (95%CI 76.6%-100.0%) , P<0.001], higher relapse[11.4% (95%CI 4.1%-29.0%) vs 3.3% (95% CI 0.6%-20.9%) , P=0.003] and higher NRM [25.7% (95% CI 8.1%-43.3%) vs 7.9% (95% CI 1.3%-26.5%) , P=0.001] after HSCT compared with that of MRD negative patients. Secondary AML showed lower DFS than primary AML [60.0% (95% CI 42.4%-76.6%) vs 86.0% (95% CI 68.4%-100.0%) , P=0.004]. ③Multivariate analysis indicated that MRD positive pre-HSCT was the independent risk factor on DFS [HR=4.565 (95%CI 2.918-9.482) , P<0.001], relapse [HR=5.854 (95%CI 1.538-22.288) , P=0.010] and NRM [HR=3.379 (95%CI 1.361-8.391) , P=0.009] after allo-HSCT in CR₁-AML. Conclusion MRD positive pre-conditioning was the only negative impact factor for patients with CR₁-AML after allo-HSCT. MRD by MFC can be used to assess the prognosis of CR₁-AML after allo-HSCT.

Objective: To investigate three different types of donor hematopoietic stem cell transplantation (HSCT) for intermediate and high-risk myelodysplastic syndrome (MDS) . Methods: Between August 2001 and May 2015, 167 consecutive patients with MDS in intermediate and high-risk who underwent allogeneic HSCT were analyzed retrospectively. Results: With the median follow up of 60 (12-177) months, The total 5-year DFS was 67.8% (95%CI 60.0%-75.6%) . Among three different types of donor, 5-year DFS rates were 68.0% (95%CI 54.1%-81.9%) in MSD-HSCT vs 77.4% (95%CI 62.1%-92.7%) in MUD-HSCT vs 64.0% (95% CI 52.4%-75.6%) in Haplo-HSCT (P=0.632) , respectively. Univariate analysis showed that median disease course before HSCT was the influencing factor of DFS (P=0.018) . Five-year relapse and TRM had no correlation with the above-mentioned factor. Conclusions Haplo-HSCT for intermediate and high-risk MDS achieved similar effect produced by MUD or MSD, Haplo-HSCT could be used as an important alternative donor. allo-HSCT must be performed on intermediate and high-risk MDS patients as early as possible after diagnosis.
