Objective To investigate the clinical characteristics and the risk factors for chronic complications in hospitalized early-onset type 2 diabetic mellitus patients. Methods The clinical data of 462 hospitalized type 2 diabetic mellitus patients were retrospectively analyzed. The patients were divided into early-onset group (age of diagnosis ≤40 years, 120 cases) and late-onset group (age of diagnosis>40 years, 342 cases) according to the age of diagnosis of diabetes. The clinical characteristics were compared and risk factors for chronic complications of early-onset type 2 diabetes were explored. Results The percentage of family history of diabetes, fasting plasma glucose, triglyceride and diastolic blood pressure in early-onset group were significantly higher than those in late-onset group:70.0％(84/120) vs. 52.3％(179/342), (8.68 ± 3.08) mmol/L vs. (8.07 ± 2.74) mmol/L, 1.69 (1.06, 2.92) mmol/L vs. 1.48 (1.07, 2.24) mmol/L and (84 ± 10) mmHg (1 mmHg = 0.133 kPa) vs. (81 ± 10) mmHg, and there were statistical differences (P<0.01 or <0.05). The incidence of hypertension, systolic blood pressure and 2h C-peptide in early-onset group were significantly lower than those in late-onset group: 44.2％(53/120) vs. 60.2％ (206/342), (134 ± 17) mmHg vs. (138 ± 18) mmHg and (3.99 ± 2.47) μg/L vs. (4.75 ± 2.65) μg/L, and there were statistical differences (P<0.01 or < 0.05). There were no statistical differences in smoking percentage, body mass index, glycated hemoglobin, total cholesterol, low-density lipoprotein cholesterol (LDL-C) and high-density lipoprotein cholesterol (HDL-C) between 2 groups (P>0.05). The incidences of peripheral vasculopathy and cerebrovascular disease in early-onset group were significantly lower than those in late-onset group:13.3％(16/120) vs. 24.3％(83/342) and 11.7％(14/120) vs. 22.8％(78/342), but the incidence of diabetic nephropathy was significantly higher than that in late-onset group: 37.5％ (45/120) vs. 27.8％ (95/342), and there were statistical differences (P<0.05 or <0.01). There were no statistical differences in incidences of coronary heart disease, diabetic retinopathy and diabetic neuropathy between 2 groups (P>0.05). Multivariate Logistic stepwise regression analysis result showed that age, duration of diabetes, hypertension, smoking, levels of glycated hemoglobin and triglyceride were the risk factors for chronic complications in early-onset type 2 diabetic mellitus patients. Conclusions The clinical characteristics are different between early-onset and late-onset type 2 diabetic mellitus patients. Early-onset patients are more prone to diabetic nephropathy, while late-onset patients are prone to macrovascular diseases such as peripheral vascular disease and cerebrovascular disease. Comprehensive management should be administered for early-onset type 2 diabetic mellitus patients to prevent chronic complications especially microvascular complications.

Objective To evaluate efficacy and safety of escitalopram in treating depression. Methods In this randomized, double-blind, double-mimicry, paroxetine parallel controlled study,the study group was treated with escitalopram and the control group with paroxetine. Hamilton Rating Scale for Depression was taken to evaluate efficacy score. Results At the end of six weeks,compared with the total scores of HAMD before and after treatment, escitalopram (17.5±7.8) and paroxetine (16.0±7.9) group both showed the significant difference, while the difference compared between two groups ,the efficacy (87.0% and 81.7%) for depression and side effects were no significance. Conclusion Escitalopram is an efficient and safety antidepressant.

Objective To observe the effects of exogenous adrenomedullin(ADM)on expressions of IL-4 and IFN-γ following mechanical renal trauma in the rats. Methods A total of 104 healthy adult plain grade Wistar rats were,randomly divided into four groups,ie,normal control group(eight rats),simple trauma group(32 rats),prevention group(32 rats,injected with ADM before trauma)and treatment group(32 rats,injected with ADM after trauma).The experimental model of rat with mechanical renal trauma was prepared by striking the ridge of the left rib area with free dropping forrous hammer in all groups except for the control group.Ten minutes before and after mechanical renal trauma,ADM ly.All rats were sacrificed by draining out all the blood in their hearts at 1,6,12 and 24 hours after mechanical renal trauma.Then,the renal tissues were removed and fixed with 10% formalin for observing the positive expressions of IL-4 and IFN-γ by means of SABC staining. Results Compared with the simple trauma group,the positive expression of IL-4 in the prevention group Wag observed at 1 hour,gradually increased at 6 and 12 hours and reached the peak at 24 hours after mechanical renal trauma,with statistical difference(P<0.05).The positive expression of IL-4 in the treatment group WaS increased at one hour and reached the peak at 6 hours after mechanical renal trauma,with statistical difference(P<0.05).Compared with the simple trauma group,the IFN-γ expression in the prevention group was,increased at 6 and 24 hours but decreased at 12 hour,while that in the treatment group was decreased significantly at 1,12 and 24 hours.Compared with the normal control group,the IFN-γ expression in the treatment group was significantly decreased at 1 and 12 hours.The IFN-γ expression in the treatment group was lower than that in the prevention group at every time points,with statistical difference(P<0.05). Conclusions Preventive and therapeutic administration of exogenous ADM can enhance the expression of IL-4.IL-4 and IFN-γ play an antagonistic role in repair ofthe renal injury.The primary role of exogenous ADM is the dynamic regulation of IFN-γ expression.

Objective To study helper T lymphocyte cell(Th)1/Th2 imbalance in rats′ model of asthma and the modulation of lentinan(LNT) on the airway inflammation and Th1/Th2 imbalance.Methods Thirty male SD rats were randomly divided into control,asthma and LNT groups.In the experiment,the rat model of asthma was established by the ovalbumin(OVA) challenge methods.Eosinophils(Eos) number and differentiated cell number in bronchoalveolar lavage fluid(BALF) were counted by different count fluids.The levels of IL-4 and IFN-? in BALF were measured by sandwich enzyme linked immunosorbent assay(ELISA).Results 1.The Eos count in BALF and the ratio of eosinophils to the total cell number(Eos%) of asthma group were significantly higher than those of the control group(t=21.94,12.81 Pa

Objective To explore the cognitive function of the theory of mind(TOM) in early-onset schizophrenia from faux pas recognition and belief understanding dimensions.Methods 41 early-onset schizophrenias (EOS) and 40 normal adolescents were interviewed by the Chinese version of faux pas recognition task and theory of mind picture-sequencing task(ToM-PST),then early-onset schizophrenias cognitive features were analyzed.Results ①In faux pas recognition task,compared with healthy subjects,EOS showed significantly less total scores (16.11±6.34 vs 20.86±7.79,P＜0.05)and subscores of understanding faux pas questions (9.88±4.11 vs 13.27± 6.07,P＜0.05).In faux pas recognition scores(6.72±2.60vs 7.58±2.20) and control questions(9.83±0.44vs 9.97± 0.16) had no statistically significant difference (P＞0.05).②In ToM-PST task,early-onset schizophrenic patients also had significantly less total score(17.29±3.38 vs 21.48± 1.73,P＜0.01),subscores of understanding first order belief,first order error belief,second order belief,second order error belief,third order error belief,sense of reality,reciprocity,fraud,detecting fraud compared to normal controls had significant difference (all P＜ 0.05 or 0.01).③ The correlation between clinical course time and PANSS score and its subscores of the theory of mind picture-sequencing and faux pas task was non-significant(P＞0.05)except the subscores of understanding the first order belief (P＜0.01).Conclusion The theory of mind is apparent damage in early onset schizophrenia and non-significant correlation is found with psychiatric symptoms.

In view of risk characteristics of surgical site infection,the risk factors of the infection were graded and classified while the risk indicators system and risk assessment matrix for surgical site infection were built,based on literature analysis,integrated use of documents analysis,Delphi method and risk quantification matrix.The study indicated that surgical skills of the surgeon and surgical time length are the most important risk factors,followed by insufficient maintenance of the operating room environment and poor baseline assessment of the patient.Risk control of surgical site infection needs to focus on these key factors,optimize utilization of resources and improve the prevention and control ability of surgical site infection.

In view of the problems of more artificial interventions and segmentation defects in existing two-dimensional segmentation methods and abnormal liver segmentation errors in three-dimensional segmentation methods, this paper presents a semi-automatic liver organ segmentation method based on the image sequence context. The method takes advantage of the existing similarity between the image sequence contexts of the prior knowledge of liver organs, and combines region growing and level set method to carry out semi-automatic segmentation of livers, along with the aid of a small amount of manual intervention to deal with liver mutation situations. The experiment results showed that the liver segmentation algorithm presented in this paper had a high precision, and a good segmentation effect on livers which have greater variability, and can meet clinical application demands quite well.
