Objective To study the changes of ventilatory function of young soldiers coming from different regions during cold - tol-erance training. Methods The recruited young soldiers were divided into 2 groups:Group Ⅰ (50 coming from the northern region)and group Ⅱ (50 coming from the southern region) . According to the new training outline of cold -tolerance in winter,their ventilatory func-tions were tested before training and 60 days after training. Ventilatory functions were compared between smoking and non - smoking sub-jects. Results 25% forced expiratory flow (FEF25%) , 50% forced expiratory flow (FEF50%) and 75% forced expiratory flow (FEF75 %) were significant different between two groups before the course of training (P < 0.05). After 60 days, ventilatory functions of two groups were improved significantly as compared with that before training (P <0.01 ,P <0.05). There was no significant difference in ventilatory between two groups after 60 days of training (P > 0.05). There was significant difference in partial small airway function be-tween smoking and non - smoking subjects. Conclusion Cold air could decline the small airway function of soldiers coming from south-ern region before training. Cold -tolerance training has significant influence on soldiers' ventilatory function. Long- term and heavy smok-ing could decline the small airway function.

Assessing dry weight accurately is crucial in providing effective and safe haemodialysis. Biases towards dry weight assessment may bring a series of dialysis complications. This study introduces an online detection technique of relative blood volume (RBV) based on ultrasound, which analyzes the correlation between changes in blood density and sound speed. By measuring the attenuation in sound velocity, this method was employed to calculate RBV, and then to evaluate the dry weight of patients on dialysis. TDC-GP2 time measurement chip and MSP430 Single-chip Microcontroller (SCM) were used in the system to measure the ultrasonic travel time. In the clinical trials, RBV values range between 71.3% and 108.1%, showing consistent result with Fresenius 4008S blood volume monitor (BVM). This detection method possesses several advantages, such as real time, convenient, reproducible, non-invasive, and etc.

Objective To explore the diagnostic value of magnetization transfer imaging (MTI) and DWI for detecting intestinal wall property of crohn's disease (CD). Methods Forty four patients with CD were prospectively enrolled in the study, and MR enterography (MRE), MTI and DWI were performed. According to MRE findings, patients were divided into three subgroups:acute inflammatory group, chronic fibrotic group and combined inflammatory with fibrotic group. Intestinal wall T2WI signal, magnetization transmisson rate (MTR) and ADC value were measured on MRE, MRI and DWI imagings, respectively. The differences of MTR and ADC among the three groups were analyzed by one-way ANOVA;the differences of T2WI scores were analysed by Kruskal Wallis;the differences of MTR and ADC values between normal and pathological intestinal wall were analyzed by paired t test;ROC curve were used to evaluate the CD fibrosis and inflammation diagnostic efficiency of MTI ana DWI based on MRE signs. Results Among the 44 cases, 11 cases were in the acute inflammatory group, 18 cases were in the chronic fibrotic group and other 15 cases were in the combination group. The T2WI score, MTR and ADC among the three groups showed significant differences (all P<0.01).The mean MTR and ADC of pathological intestinal wall of the 44 cases were (40.77±6.05)%and (1.04±0.18)× 10-3mm2/s, and the adjacent normal bowel were (21.75±4.17)%and (1.97 ± 0.23) × 10- 3mm2/s, respectively. Moreover, the difference of the above values showed significant differences (t=19.12,-21.80 respectively, all P<0.01). There was a negative correlation between MTR and T2WI score (r=-0.71,P<0.01). While ADC value was positively correlated with T2WI score (r=0.80, P<0.01). Using ROC curve analysis to differentiate the CD fibrosis from acute inflammation, the area under the curve (AUC) of MTR and ADC were 0.97 and 0.96 ,respectively. Conclusions Both MTI and DWI can be used to assess the properties of intestinal wall, which has the same diagnostic efficacy to identify the acute inflammation and fibrosis.

Objective To investigate serum alpha2-Heremans-Schmid glycoprotein ( AHSG ) level and its relationship with associated clinical parameters in subjects with simple overweight and obesity. Methods Forty-nine subjects with obesity ( OB group) , 176 subjects with overweight ( OW group) , and 327 individuals with normal weight ( NW group) were randomly enrolled. The clinical data were collected and serum levels of AHSG and adiponectin ( APN) were determined by ELISA. The associations of serum AHSG level with other clinical parameters were assessed by Pearson correlation analysis and multiple linear regressive model. Results Serum AHSG levels were higher in OW and OB groups than that in NW group[(276. 30 and 302. 10 vs 241. 60)μg/ml], being especially higher in OB group (P<0. 05 or P<0. 01). Serum AHSG level in NW group was positively associated with fasting plasma glucose, homoeostasis model assessment of insulin resistance index, C-reactive protein (CRP), triglycerides, and free fatty acids ( FFA ) , but negatively associated with age and APN. In OW and OB groups, AHSG was also positively associated with body mass index, waist hip ratio(WHR), and low density lipoprotein cholesterol(P<0. 05 or P<0. 01) except the aforementioned clinical parameters. In multiple linear regression model, AHSG was positively associated with WHR, CRP, and FFA, and was negatively associated with APN ( P<0. 05 or P<0. 01). Conclusion The raised AHSG level in overweight and obese subjects may be a risk factor for obesity-related diseases.

Objective To identify the clinical and imaging characteristics in neonatal refractory purulent meningitis. Methods Clinical data of 70 cases of neonatal purulent meningitis admitted to the neonatal intensive care unit at Children's Hospital of Fudan University from January, 2009 to December, 2014 were reviewed retrospectively. The patients were divided into refractory group (n=28) and non-refractory group (n=42) according to the course of antimicrobial therapy.The clinical and brain MRI characteristics of neonatal refractory purulent meningitis were analyzed. Parameters were compared between the two groups using Chi-square or Fisher's exact tests, and Wilcoxon tests where appropriate. Risk factors of neonatal refractory purulent meningitis were investigated by univariate and multivariate Logistic regression analysis. Results Among the 70 cases, 31(44.3%) were positive for cerebrospinal fluid (CSF)/blood culture. The positive rate was higher in the refractory group than in the non-refractory group [75.0%(21/28) vs 23.8%(10/42),χ2=17.843, P<0.01]. The most common pathogenic bacteria isolated in the refractory group were Escherichia coli [8 cases (38.1%)] and group B streptococci [5 cases (23.8%)]. Compared to the non-refractory group, patients in the refractory group were more likely to have seizure, higher CSF white blood cell count, higher CSF protein concentration and lower CSF glucose concentration [53.6%(15/28) vs 7.1% (3/42), 965.0 (463.0-2 200.0)×106/L vs 116.5 (61.0-327.5)×106/L, 3 221.1(2 354.3-4 633.5) mg/L vs 1 487.6(988.2-1 924.1) mg/L, and 0.2 (0.1-0.8) mmol/L vs 1.5 (1.2-1.8) mmol/L; all P<0.01]. Multivariate Logistic regression analysis showed that seizure, low CSF glucose concentration on admission, and a positive CSF/blood culture result neonatal refractory purulent meningitis (OR=9.6, 95%CI: 1.2-76.0; OR=15.0, 95%CI: 5.6-63.3; and OR=7.3, 95%CI: 1.5-36.0, respectively). Abnormal brain MRI findings, including intracranial extracerebral space abnormality, ventricular dilatation and periventricular white matter injury, were more common in the refractory group [100.0%(28/28) vs 61.9%(26/42), χ2=13.827 totally; 64.3%(18/28) vs 21.4%(9/42), χ2=13.023 for intracranial extracerebral space abnormality; 60.7%(17/28) vs 19.0%(8/42), χ2=12.704 for ventricular dilation and 28.6%(8/28) vs 2.4%(1/42) for periventricular white matter injury; all P <0.01]. Compared with the non-refractory group, the refractory group had a longer hospital stay [(48.0±17.4) d vs (26.0±10.2) d, t=6.016, P<0.01] and more adverse events [67.9%(19/28) vs 31.0%(13/42), χ2=9.220, P=0.002], including hearing impairment and requirement of neurosurgical intervention [14/18 ears vs 10/46 ears (21.7%), χ2=4.292, P=0.038]. There was no death in both groups during hospitalization. Conclusions Neonates with seizure, low CSF glucose concentration and positive CSF/blood culture results are more likely to have refractory purulent meningitis. Brain MRI abnormalities are more common in neonatal refractory purulent meningitis.

BACKGROUND:Considering the risk of lack of bone in revision and the bone coverage of component,it is advisable to use bone grafting to increase bone stock in patients with adult Crowe type Ⅲ developmental dysplasia of the hip (DDH) in the first total hip arthroplasty (THA).OBJECTIVE:To investigate the effectiveness of impaction bone grafting with morselized bone and bone paste for acetabular defects of adult Crowe type Ⅲ DDH in THA.METHODS:Forty cases (45 hips) of Crowe type Ⅲ DDH were enrolled,including 8 males and 32 females,aged 31-68 years.All the components were reconstructed at the anatomic acetabulum combined with deepening acetabulum and putting the centre of rotation medially and distally during THA procedures.The patients were all followed up and evaluated with Harris score,limp length,displacement of the centre of rotation,cup coverage,and postoperative complications.RESULTS AND CONCLUSION:The average follow-up was 32.7 months.Acetabular rotation centers of all the cases were recovered (near) to normal.The incisions healed by first intention and there was no complication such as infection,dislocation,prosthesis loosening.The acetabular cup prosthesis did not displace and was covered well by bone at the last follow-up,the grafted bone particles got radiological osseointegration and the bone sclerosis zone disappeared.No radiolucent lines and screw fracture were detected.The Harris scores of affected hips at the last follow-up were significantly higher than those before surgery(P=0).The average leg length was increased (2.31 ±0.18) cm.The mean cup coverage was 78.1％.The postoperative horizontal and vertical distance of the hip center were shorter than those before surgery (P=0).Reconstructing the acetabulum with autogenous morselized bone graft impaction can effectively restore the acetabular coverage,maintain the stability of acetabular cup and provide better relative bone stock in THA for Crowe type Ⅲ DDH in adult,and moreover,the short-term effect is satisfactory.

Objective To explore the effect of exercise preconditioning on apoptosis and expression of P53 protein in ischemic penum-bra in rats after cerebral ischemia-reperfusion. Methods Thirty-six Sprague-Dawley rats were randomly divided into sham group, model group and exercise preconditioning group, with twelve rats in each group. The middle cerebral artery occlusion (MCAO) model was estab-lished with modified Longa's method. TUNEL method was used to observe the apoptosis of neural cells in the ischemic penumbra. Western blotting was used to detect the expression of P53 protein in the ischemic penumbra. Results Twenty-four hours after cerebral ischemia-reper-fusion, the number of TUNEL positive cells was more in the model group than in the sham group (P<0.01), and was less in the exercise pre-conditioning group than in the model group (P<0.01). The expression of P53 protein was higher in the model group than in the sham group (P<0.01), and was lower in the exercise preconditioning group than in the model group (P<0.01). Conclusion Exercise preconditioning coud down-regulate the expression of P53 protein in the ischemic penumbra, and inhibit the apoptosis of cortical cells.
