Objective To investigate etiology and clinical features of acute pancreatitis (AP) in young patients. Methods In total, 423 patients with AP admitted to Renmin Hospital of Wuhan University, Wuhan, Hubei province during January 2006 to December 2009 were retrospectively analyzed, 55 cases aged 34 years or less as young group and another 55 cases aged more than 34 years as middle- and elderly-age group. Their etiology, clinical features and illness scores based on some standard criteria were assessed. Results Proportion of varied etiologies of AP in young group was different from that in middle- and elderly-age one (x2 = 17. 107, P = 0. 009) , mainly as biliary and idiopathic pancreatitis in young group and as biliary and alcoholic pancreatitis in middle- and elderly-age one. Incidence of diet-related and idiopathic pancreatitis were higher in young group than that in middle- and elderly-age one ( x2 =4. 853, P = 0. 028 and x2=4. 274, P = 0. 039 ). Scores of the acute physiology and chronic health evaluation II ( APACHE II ) , Ranson criteria and the bedside index for severity in acute pancreatitis ( BISAP) were all lower in young group than those in middle- and elderly-age one (t = 5. 381 , P = 0. 000; t = 4. 388 , P = 0. 000 and t=3. 083, P = 0. 003 ) . There was no statistically significant difference in scores of computed tomography severity index ( CTSI) between young group and middle- and elderly-age one (t = ±0. 750, P > 0. 05 ) . Recurrence rate of AP was lower in young group than that in middle- and elderly-age one ( x2 =4. 251, P = 0. 039). Cholecystitis was more complicated in young group, pregnancy was more complicated in young group (x2 =4. 151 , P =0. 042) , and elevated blood glucose was more complicated in middle- and elderly-age one (x2 = 13. 285 , P = 0. 000 ) . Conclusions Etiology of AP varies in young patients with more dietary factors, occurrence of systemic complications and risks for death are lower in young group than those in middle- and elderly-age one, and there was no statistically significant difference in local complications and severity of illness between the two groups.

Objective To explore the differences in behavior of anxiety individuals and the normal control under different feedback (positive feedback,negative feedback).Methods 400 university students were investigated using self-rating anxiety scale(SAS) and state anxiety inventory (SAI) and the data were analyzed with balloon analogue risk task.Results The score of anxiety group(24.28±6.12) was significantly lower (t=-2.25,P＜0.05) than that of control group(29.80±7.26) in the number of busting balloons.But in the number of busting balloons of positive and negative feedback condition,scores of anxiety group and control group were not significantly different(t=-1.82,P＞0.05;t=-1.78,P＞0.05).Conclusions Influence of anxiety on decision-making often manifests as risk aversion.

Objective To observe the expression of insulin receptor mRNA in skeletal muscle and the change of oxidative stress in diabetic rats at different intensity training.Methods Sprague-Dawley rats were divided into group A(control group),group B(non-exercise group),group C(low-intensity exercise group),group D(moderate-intensity exercise group) and group E(high-intensity exercise group),6 rats in each group.A diabetic rat model was induced by injecting streptozotocin(STZ)for 4 weeks after high lipid and glucose breeding.Rats were trained for 6 weeks on a treadmill.Serum glucose and insulin,insulin resistance index(HOMA-IR),activities of SOD and GSH-Px,and MDA were detected before and after training.Expression levels of InsR mRNA in skeletal muscle were measured by RT-PCR.Results The InsR receptor mRNA expression level in three exercise groups at different intensities was 0.55?0.05,0.53?0.04,and 0.41?0.05,respectively,and was significantly higher in low and moderate intensity exercise groups than in group B (P

Objective To analyze the status of healthcare-associated infection(HAI)and characteristics of patho-gens in patients with traumatic brain inj ury and cerebrovascular diseases,and evaluate prevention and control meas-ures.Methods Clinical data of 236 patients with traumatic brain injury and cerebrovascular diseases in a hospital from 2008 to 2010 were analyzed retrospectively.Results A total of 29 patients developed 50 times of HAI,HAI rate was 12.29%,HAI case rate was 21.19%,HAI case rate of respiratory system,urinary system,oral cavity, gastrointestinal tract,skin and soft tissue,and other sites was 46.00%(n=23),30.00%(n=15),8.00%(n=4), 6.00%(n=3),4.00%(n=2),and 6.00%(n=3)respectively.A total of 69 pathogenic strains were detected,per-centage of gram-negative bacteria was 65.22%(n=45),the major were Pseudomonasaeruginosa(n=17),Klebsiel-lapneumoniae(n=12),Escherichiacoli(n=10),and Acinetobacterbaumannii(n=4);percentage of gram-positive bacteria was 30.43%(n=21),the major were Staphylococcusaureus(n=11),Staphylococcusepidermidis (n=7), Streptococcus spp.(n=2);percentage of fungi was 4.35%(n=3).Conclusion HAI in patients with traumatic brain inj ury and cerebrovascular diseases is high,the main infection site is respiratory system,the main pathogens are gram-negative bacteria.Preventive and control measures should be taken accordingly.

OBJECTIVE To find out fulminate epidemiological features of Stenotrophomonas maltophilia in ICU and the ways to prevent and treat this nosocomial infection.METHODS The case histories from 4 inpatients who developed S.maltophilia infection in the same ward from Feb 5 to 16,2006,were studied retrospectively to find out the reasons of its onset and its treatment based on the sputum culture results.RESULTS The fulminate S.maltophilia was found from the rail of the patient bed,the connection part of water container of 2 respiratory machines of exhalation valve assembly and the liquid of ultrasonic aeriation machine.CONCLUSIONS The infection is a localized one.The main reasons of the infection are unthorough disinfection of respiratory machine and the contamination of medical treatment environment.Whenever the infection is found in the ward,the thorough disinfection needs immediately,and no new patient admitted.

BACKGROUND:Diabetes mel itus can give rise to bone metabolic disorders that may involve long-term hyperglycemia, hypoglycemic agents, diet control, estrogen, insulin-like growth factor, leptin, body mass, sex and age.
OBJECTIVE:To establish type 2 diabetic rat models, and to explore the influence of type 2 diabetes on bone metabolism.
METHODS:High-fat and high-glucose diets combining with 35 mg/kg streptozotocin were used to induce type 2 diabetic model in seven male Sprague-Dawley rats (diabetic group). Thirteen rats in control group were given intraperitoneal injection of the same amount of citric acid and sodium citrate buffer. At 4 weeks after modeling, the bone density of rats was serum detected by dual-energy X-ray, levels of fasting blood-glucose, cholesterol, triacylglycerol, serum calcium, phosphate, alkaline phosphatase, fasting insulin, osteocalcin and C-terminal telopeptide-I were measured, and morphology of bone was observed.
RESULTS AND CONCLUSION:Compared with control group, (1) the rat body mass and fasting blood-glucose kept on an overt rise in the diabetic group (P<0.05);(2) levels of cholesterol, triacylglycerol, fasting insulin and alkaline phosphatase, as wel as insulin resistance index were significantly increased, but insulin sensitivity index was significantly decreased in the diabetic group (P<0.05). (3) There were no significant differences in the levels of serum calcium, phosphate, alkaline phosphatase, osteocalcin and C-terminal telopeptide-I between two groups (P>0.05). (4) In the diabetic group, thinner and sparse bone trabeculae were split presenting more free broken ends;(5) the bone density in lumbar spine, double femoral, pelvic and thoracolumbar spine were al significantly decreased (P<0.05). (6) In conclusion, the type 2 diabetic rat model can be successful y induced by 5-week feeding high-fat and high-glucose diets combining with intraperitoneal injection of 35 mg/kg streptozotocin;these mode rats hold some characters, such as hyperglycemia, dyslipidemia, insulin resistance, diminished bone density, and accelerated bone resorption.

INTRODUCTIONErythroderma is a generalised inflammatory reaction of the skin secondary to a variety of causes. This retrospective study aims to characterise the features of erythroderma and identify the associated causes of this condition in our population.

MATERIALS AND METHODSWe reviewed the clinical, laboratory, histological and other disease-specific investigations of 225 inpatients and outpatients with erythroderma over a 7.5-year period between January 2005 and June 2012.

RESULTSThe most common causative factors were underlying dermatoses (68.9%), idiopathic causes (14.2%), drug reactions (10.7%), and malignancies (4.0%). When drugs and underlying dermatoses were excluded, malignancy-associated cases constituted 19.6% of the cases. Fifty-five percent of malignancies were solid-organ malignancies, which is much higher than those previously reported (0.0% to 25%). Endogenous eczema was the most common dermatoses (69.0%), while traditional medications (20.8%) and anti-tuberculous medications (16.7%) were commonly implicated drugs. In patients with cutaneous T-cell lymphoma (CTCL), skin biopsy was suggestive or diagnostic in all cases. A total of 52.4% of patients with drug-related erythroderma had eosinophilia on skin biopsy. Electrolyte abnormalities and renal impairment were seen in 26.2% and 16.9% of patients respectively. Relapse rate at 1-year was 17.8%, with no associated mortality.

CONCLUSIONOur study highlights the significant proportion of malignancy-related erythroderma in those whom common underlying causes such as dermatoses and drugs have been excluded. In cases of drug-related erythroderma, traditional medications and antituberculous medications are common causes in our population. Renal impairment and electrolyte abnormalities are commonly seen and should be monitored in patients with erythroderma.
