OBJECTIVE To lower the incidence of postoperative pulmonary infection in abdominal major operation.METHODS We performed a retrospective trial analysis on pulmonary infection after major abdominal operation in 402 cases from Oct 2004 to Oct 2005,and in the meanwhile effective preventive procedures were conducted.RESULTS Thirty three cases with pulmonary infection went weel with active treatment and nursing.CONCLUSIONS The predisposing factors for postoperative infection include anesthetic method,incision pain,and environmental pollution.The better methods for prevention of pulmonory infection are good preoperative instruction,planned respiration training,keeping airway confluent postoperatively,effectively reducing incision pain,infection control,and preventing environmental and air pollution.

Objective To describe the depression of premature infants′ mothers and discuss the related influence factors. Methods A total of 86 premature infants′ mothers completed Edinburgh Postnatal Depression Scale at 3-days postpartum in this descriptive study during August 2014 to January 2015 in Obstetrics and Gynecology Hospital of Fudan University. Results The prevalence of postpartum depression in premature infants′ mothers was 25.6% (22/86). Educational levels, family support, character, and number of abortion of mothers, pregnancy complication, gestational age, birth weight, Apgar score, length of hospitalization, and birth with abnormalities of premature infants were found significantly associated with postpartum depression (P<0.05). By Logistic regression, family support (OR=3.253, 95% CI=1.180-8.966) and length of hospitalization (OR=2.905, 95% CI=1.418-5.952) were the risk factors of the postpartum depression at 3-days after delivery. Conclusions Premature infants′mothers at 3-days postpartum presented with obvious postpartum depression. Psychological intervention should be focused on its influence factors.

Analysis was made in 3 patients with central nervous system lymphoma(CNSL) with different manifestations;neuroradiological and immunocytological investigations were used to improve the clinical diagnosis of CNSL.Three patients with CNSL presented with 3 distinct profiles:diffuse meningeal invasion, intracranial masses of tumor and intramedullary spinal invasion. Both contrast enhanced CT and MR provided CNSL lesions in the brain parenchyma and meninges. It is suggested that combining CT,MR findings and immunological markers can improve clinical diagnosis of CNSL.

Vectors used to carry foreign genes play an important role in gene therapy, among which, the adeno-associated virus (AAV) has many advantages, such as nonpathogenicity, low immunogenicity, stable and long-term expression and multiple-tissue-type infection, etc. These advantages have made AAV one of the most potential vectors in gene therapy, and widely used in many clinical researches, for example, Parkinson's disease. This paper introduces the biological characteristics of AAV and the latest research progress of AAV carrying neurotrophic factor, dopamine synthesis related enzymes and glutamic acid decarboxylase gene in the gene therapy of Parkinson's disease.

Objective To evaluate the relationship of metabolic syndrome (MS) and MS components with thyroid nodule. Methods A total of 10 357 subjects ( age ＞ 18 years old) who received physical checkup at the Second Affiliated Hospital of Dalian Medical University between June 2009 and June 2010 were enrolled in this retrospective study. Anthropometric parameter, fasting plasma glucose (FPG),serum lipid profile, blood uric acid, alanine aminotransferase and thyroid ultrasonography were measured. Results The prevalence of thyroid nodule,MS,and thyroid nodule + MS was 46. 96% ,23. 6%,and 11.6%, respectively. The prevalence of thyroid nodule was significantly higher in MS patients than in non MS patients ( 75.9% vs 38. 0%, P ＜ 0. 05 ). Multifactor logistic analysis showed that MS, body mass index (BMI) and FBG (β vales were 0. 78,1.22,and 0. 62,respectively; odds ratios were 4. 167,3. 876,and 2. 359, respectively; all P ＜ 0. 05 ) were independently correlated with the development of thyroid nodule. Conclusions Significantly increased prevalence of thyroid nodule could be found in MS patients. BMI and FBG may be independent risk factors of thyroid nodule.

Objective To determine the relationship between normal weight obesity (NOW) and cardiovascular risk factors.MethodsA total of 940 adults who received a health examination in out hospital were recruited in a cross-sectional study,and 407 with a body mass index (BMI) of18.5 to 25 kg/m2were enrolled for further analysis.Body fat percentage ( BF％ ) was measured by bioelectrical impedance analysis (BIA),and the subjects were assigned to the NOW group ( BF％ ≥25％ for male or BF％ ≥35％for female) or the control group ( BF％ ＜ 25％ for male or BF％ ＜ 35％ for female).Cardiovascular risk factors and their detection rates were compared between the two groups by using independent sample t test and x2 test.The correlationbetweenNOW and cardiovascular risk factors was assessedbylogistic regression.Results The prevalence of NOW in men and women were13.1％ and14.9％,respectively.The prevalence of NOW was increased with age ( x2 =6.90,P ＜0.05 ).Systolic blood pressure (SBP),diastolic blood pressure ( DBP ),total cholesterol ( TC ),triglycerides ( TG ),low-density lipoprotein cholesterol ( LDL-C) and serum uric acid (SUA) were significantly increased in the NOW group (t values were 2.97,2.44,2.54,5.09,2.71and 3.91,respectively; all P ＜ 0.05 ) ; whereas high-density lipoprotein cholesterol ( HDL-C) was significantly decreased in the NOW group (t =-3.90,P ＜ 0.05 ).The prevalence of hypertension,hyperglycemia,high triglyceride,low HDL-C,dyslipidmia and hyperuricemia was increased in the NOW group in comparison with the control group ( x2 values were 6.76,5.58,14.50,11.97,10.97 and 8.76,respectively;allP＜ 0.05 ).LogisticregressionshowedNOWincreasedtheriskof hypertension,hyperglycemia,dyslipidmia or hyperuricemia by 2.186,2.120,2.088 or 4.175 times.After adjustment for age and gender,the risk for hyperuricemia was decreased to 3.491,but remained statistically significant higher.Conclusions NOW may be correlated with cardiovascular risk factors,and those with NOW could be at higher risk for cardiovascular diseases.

Objective To investigate the psychological health states of practical nurse and to effectively conduct clinical psychological guidance.Methods 368 practical nurse were determined by SCL-90 and compared with normal control.Results There were significant differences between practical nurse and normal control,such as compulsion,sensitive interpersonal,depression,anxiety,terror crankiness(P<0.05～P<0.01),and no remarkable difference in other factors(P>0.05).Conclusion Nurse's gross mental health level were worse than normal control,especially in compulsion,sensitive interpersonal,depression,anxiety,terror crankiness. So, mental health education should be enhanced for them.

Objective:To investigate the relationship between electrophysiology and pathology changes in diabetic peripheral neuropathy (DPN) rats and to assess the value of electrophysiology in diagnosis of DPN. Methods: Twenty-four healthy male SD rats were intraperitoneally injected with a single dose of streptozotocin to induce DPN models and the rats were subsequently divided into 3 groups, namely, the DPN model group, the low dose Tong-Luo composite recipe (TLCR) group, and the high dose TLCR group. Rats in the latter 2 groups were lavaged with 2 ml double-distilled water containing 0.5 g/kg and 2 g/kg TLCR for 8 weeks, respectively. Antother 8 healthy rats were taken as normal controls. The motor conduction velocity (MCV), sensory conduction velocity (SCV), and potential latency and amplitude of caudal nerves were measured after 8 weeks in all rats. Morphometric quantitative analysis was also performed. Results: Compared with normal control group, the MCV, SCV, and potential amplitude of the caudal nerve in DPN model group were decreased, but the potential latency was increased. After TLCR treatment, the above indices were significantly improved and were close to those of the normal control group. SCV of the low dosage group was still significantly lower than that of normal control group (P
