Objective To explore the correlation between oxidative stress and the occurrence and progression of diabetic complications in the patients with diabetes. Methods The content of 24 h urinary 8-hydroxy-deoxyguanosine (8-OhdG) in diabetes mellitus (DM) group, diabetic nephropathy (DN) group, diabetic retinopathy (DR)group, diabetic foot(DF) group, diabetic neuropathy (DNP) group and control group were detected, and analyzed. Results The content of 24 h 8-OhdG in DM group, DN group, DR group, DF group, DNP group were significantly higher than that in the control group (P ＜ 0.01), and that in DN group, DR group, DF group, DNP group were significantly higher than that in DM group(P ＜ 0. 01), but the content of 24 h 8-OhdG among DN group, DR group, DF group and DNP group was not statistically signiticant(P ＞0. 05). Conclusion The correlation between the occurrence of diabetic and its complications oxidative stress and the Ievel of oxidative stress in the body was positive related.

Objective To investigate the effect on free portal pressure (FPP), postoperative complications and rebleeding of devascularization procedure with intact portasystemic collateral shunts. Methods The clinical data of 121 patients with portal hypertension undergoing devascularization in our hospital from 1994 to 2004 were retrospectively analyzed. Patients were divided into two groups(96 cases and 25 cases) , respectively according to whether or not the portasystemic collateral shunts were reserved during operation. Results (1) Free portal pressure (FPP) decreased significantly after devascularization in both two groups [(47?8) cmH2O vs. (37?5) cmH2O, (41?7) cmH2O vs. (37?6) cmH2O; P

Aim To examine the effect of Nampt over-expression on cardiac hypertrophy,and elucidate the role of NF-κB.Methods The cultured neonatal car-diomyocytes were pretreated with 100 μmol · L-1 PE or transfected with Nampt.The mRNA and protein ex-pression of Nampt were determined by Real-time PCR and Western blot respectively.The cardiomyocyte hy-pertrophy was monitored by measuring cell-surface area and the mRNA levels of ANP and BNP,which were biomarkers of hypertrophic response.Moreover,we te-sted the effects of Nampt on NF-κB-dependent tran-scription activity through luciferase reporter gene as-says.Results Nampt overexpression significantly in-creased cardiomyocyte surface area and the mRNA ex-pression of ANP and BNP.In addition,Nampt overex-pression could markedly increase NF-κB-dependent transcription activity. Moreover, when p65 was knocked down,cardiomyocytes with Nampt overexpres-sion could not induce cardiac hypertrophy.Conclusion
Overexpression of Nampt induces cardiac hypertro-phy by increasing NF-κB-dependent transcription activ-ity.

Objective To analyze the factors that influence the family training compliance of THR,to provide a theoretical basis for the early rehabilitation of the patients' limbs function.Methods A questionnaire survey was used in this study,52 patients who received THR six months ago were given family visit.The survey including the scores of the patients' basic information,compliance of rehabilitation training and the rehabilitation of hip function,and statistical analysis was given to acquired data.Results The score of the postoperation family rehabilitation training compliance was (30.76±5.28).The order of the four dimensions was ranked as:the self-care capacity,the good habits,rehabilitation training skills and the relevant knowledge of the disease.The major related factors of the compliance were the education level,psychological condition,family and social support condition and economic condition.Conclusions Factors such as knowledge of rehabilitation,rehabilitation training skills,education level,psychological condition,family and social support and the economic condition are related to the compliance of family rehabilitation training.An effective rehabilitation training plan,postoperation visiting,recovery instruction and stable social support can play a positive influence on the compliance of family rehabilitation training and the recovery of limbs'function as well as the patients' quality of life.

Objective To evaluate the clinical efficacy of standardized house dust mite allergen specific immunotherapy (SIT) for rhinitis and asthma in children. Methods Forty-two children with allergic rhinitis and asthma who received a standardized house dust mite allergen SIT in our hospital were enrolled in our study. The result of allergen skin prick test, serum specific IgE levels (sIgE) of house dust mite and dust mite,pulmonary function and symptom scores were analysed before and at one year after treatment in all children. Results Skin indexes of house dust mite and dust mite, symptom score were significantly decreased at one year after treatment,but the levels of house dust mite and dust mite sIgE,lung function test (FVC,FEVt,MEF25-75) showed no significant differences. Conclusion Children with allergic rhinitis and asthma have significant improvements in their skin sensitivity and clinical symptoms by given SIT for one year,but the impact of SIT on airway inflammation needs further observation.

Objective: To analyze the association of thrombocytosis with the prognosis of patients with gastric cancer.Methods: The clinical materials of 782 patients with gastric cancer who underwent initial surgery in our hospital between January 1995 and December 1999 were retrospectively analyzed.Kaplan- Meier and Log-Rank test were used to analyze the data.Prognostic factors were analyzed by multivariate Cox proportional hazards model.Results: Thrombocytosis oc-curred in 11.4% (87/782) patients.The platelet level was not significantly different among patients of different gender, tumor stage, and histological differentiation (P>0.05).However, a significant difference was observed in the platelet level among patients with different age and surgical approach (P<0.05).The 1-, 3-, and 5-year survival rates were 75.0%, 40.1% and 28.9% in patients without thrombocytosis and 52.8%, 16.9%, and 13.5% in patients with thrombocytosis (P=0.002).Univari-ate analysis showed that histological differentiation, pathological stage, surgical approach and thrombocytosis significantly affected the survival of patients.While age and gender had no significant impact on patient survival.Multivariate analysis showed that pathological stage, surgical approach, and thrombocytosis were independent prognostic factors for gastric can-cer.The relative risk of death of patients with thrombocytosis was elevated by 1.454 times (RR=1.454, 95% CI: 1.135～1.861, P=0.005).Conclusion: Thrombocytosis is an independent prognostic indicator for the survival of initially treated pa-tients with gastric cancer.

Objective The stress reaction in double-balloon enteroscopy was investigated,the influencing factors and intervention countermeasures were studied.Methods Cardiovascular effects and physiological reactions of 60 double-balloon enteroscopy patients were surveyed.The patients were divided into 2 groups according to the cardiovascular effects to underwent single factor analysis of related factors.Results The incidence of physiological reactions was 68.3%,the incidence of cardiovascular reactions was 56.7%.Evident difference existed in blood pressure,heart rate and blood oxygen saturation rate before,during and after examination.The grouping analysis showed cardiovascular effects were influenced by many kinds of factors.Conclusions Different degrees of the stress reactions in double-balloon enteroscopy might appear.The influencing factors included the enteroscopy mode and time,gender,age,mood,and physician operation experience.The stress reactions might be reduced by taking the corresponding intervention measures according to the influencing factors.

Objective Through investigating the clinicians’ scientific research level and weakness,we can carry out targeted clinical research training systematically,and then strengthen their utilization of clinical resources and data,and finally promote the transformation of scientific research resuits.Methods Filling and submitting the online questionnaires through WeChat,a popular chatting tool in China,physicians from 13 affiliated hospitals of a university in Shanghai have joined this research.Results 507 valid questionnaires have been received online:In terms of clinical research capacity,there seemed to be more barriers in the following issues:comprehension of the types and applications to design a clinical trial,formulation of the details including PICO elements(Patient-Intervention-Comparison-Outcome),methodological application including the category and principle of randomization,the category and principle of blind method and how to control the confounding elements and probable bias,and statistical problems in scientific research including discrimination of the different definition between FAS(Full Analysis Set) based on the principle of ITT(Intention-To-Treat) and PPS(Per-Protocol Set),how to write a standardized SAP(Statistical Analysis Plan) and how to calculate the sample size of a trial),and various management of clinical trials including data management,follow-up management,adverse event management and so on,and writing a protocol and a CRF (Case Report Form) in a standard and professional way.As for the needs for training,the top three topics were how to design a clinical research in a standardized style,how to practice the methodology and how to utilize the statistical skills into clinical trials.Conclusions Standardized design and writing of clinical trial protocols according to the CONSORT (Consolidated Standards of Reporting Trials) and SPIRIT (Standard Protocol Items:Recommendations for Interventional Trials),and the application of epidemiological and statistical methods are still short boards that most clinicians need to improve urgently,also are what they most concerned about at the same time.So it is necessary for physicians to receive systematic clinical research training to enhance their scientific research capacity.

Objective: To investigate the clinical characteristics of early term and full term neonates, and analyze the risk factors associated with short term outcomes in early term neonates. Method: Neonates with birth weight (BW) ≥2 500 g from year 2013 were analyzed retrospectively based on American Congress of Obstericians & Gynecologists (ACOG) latest definition of term infants. According to inclusion and exclusion criteria, early term (gestational age 37-38 weeks) and full term(gestational age 39-40 weeks) neonates were included, whose morbidity constituent proportion was analyzed by χ² test or Fisher accuracy test or t test or Wilcoxon test. Risk factors associated with short term outcomes in early term population were analyzed by Logistic regression analysis. Result: There were 3 002 discharged term infants being investigated, among whom 1 303 cases were included(768 males and 535 females), and 37, 38, 39 and 40 weeks′ gestational age newborns were 160, 324, 450 and 369 respectively. Compared with full term neonates(n=819), early term neonates (n=484) had longer length of hospital stay (LOS)(6.0(5.0, 9.0) vs. 6.0(4.0, 8.0), Z=2.830, P=0.005), higher usage rate of intravenous antibiotics(86.4%(418/484) vs. 80.1%(656/819), χ²=8.009, P=0.005), higher assisted ventilation rate(9.5%(46/484) vs. 2.9%(24/819), χ²=25.528, P<0.01), higher pulmonary surfactant administration rate(4.3%(21/484) vs. 1.1%(9/819), χ²=14.006, P<0.01), as well as higher hypoglycemia incidence(3.9%(19/484) vs. 1.2%(10/819), χ²=10.226, P=0.001). There were no statistically significant differences in 1 min Apgar score (9(9, 10)vs. 9(9, 10), Z=0.860, P=0.390), 5 min Apgar score (10(9, 10) vs. 10(9, 10), Z=0.810, P=0.418), white blood cell count (15 (11, 21) ×10⁹ /L vs.15 (11, 22) ×10⁹ /L, Z=0.880, P=0.379), hemoglobin count(180 (159, 205) vs. 182 (160, 204) g/L, Z=0.560, P=0.576), or platelet count(303(234, 372) ×10⁹/L vs. 301(237, 391) ×10⁹/L, Z=0.550, P=0.584). BW between 2 500 g and 2 999 g(OR 1.69, 95% CI: 1.10-2.62, χ² =5.614, P=0.018), wet lung(OR=2.61, 95% CI: 1.61-4.24, χ²=15.023, P=0.000)and pneumonia(OR 1.88, 95% CI: 1.14-3.08, χ²=6.192, P=0.013) were risk factors in early term neonates′ short term adverse outcomes. Conclusion Early term newborns are still at their "immature" state, and respiratory disorders are major risk factors associated with short term outcomes. Hence, early delivery during 37-38 weeks should be avoided as possible as we can.
