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.

Methods 125 I was implanted intraoperatively into the residual pancreatic cancer tissues after gastric carcinoma was palliatively removed. Results From Feb. 2005 to Jun. 2009, 15 cases (9 male, 6 female) advanced gastric cancer patients were treated with 125 I intra-operative implantation. The patients' ages ranged from 41 to 78 years, with the median age of 64 years old. There were 10 cases of gastric cancer infiltrating the neck or body of pancreas and 5 cases infiltrating pancreatic head. No severe post-operative complications were recorded. The follow-up showed that there were 5 cases of CR (33.3%), 9 cases of PR (60%), 1 case of NC (6.7%) and no PD patients were found. Conclusion 125I intra-operative implantation plus palliative gastric resection is feasible and effective for patients of advanced gastric cancer infiltrating the pancreas.

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.

BACKGROUND:Legacy posterior stabilized prosthesis has advantages in theoretic design,in vitro kinematics and abrasion, but it remains unclear whether its clinical outcomes for vaglus knee deformity are better than Legacy constrained condylar knee prosthesis. OBJECTIVE:To explore the midterm folow-up effect of Legacy posterior stabilized prosthesis in total knee arthroplasty in patients with valgus knee deformity. METHODS: From February 2006 to November 2013 in Department of Bone and Joint Surgery, Affiliated Hospital of Luzhou Medical Colege, total knee arthroplasty was used to treat valgus knee deformity in 33 cases (35 knees). Parapatelar medial approach was used. Precise osteotomy was utilized to correct limb alignment. Lateral soft tissue received selective release. Finaly, an equal type of Legacy posterior stabilized prosthesis (Zimmer, USA) was implanted and fixed with antibiotic bone cement. The differences in hospital for special surgery knee score, range of motion of knee, femoral tibial angle, and maximum flexion and extension angle, as wel as X-ray film results were compared and analyzed before and after replacement. The complications including deep vein thrombosis, peri-prosthetic infection, patelar clicking, unstable knee, and common peroneal nerve injury were recorded after surgery. RESULTS AND CONCLUSION: Al patients were folowed up for 24-50 months. The incision was healed in one-stage. No complications such as peri-prosthetic infection appeared. Three patients suffered from common peroneal nerve palsy, which was cured at half a year after surgery by expectant treatment such as trophic nerve. Two cases suffered from knee instability after replacement, which was improved at 1 month after external fixation with a brace. One case experienced deep vein thrombosis in the lower extremity, which was improved after treatment with low molecular weight heparin anticoagulation. During final folow-up, hospital for special surgery knee score increased from (51.85±4.15) preoperatively to (85.77±2.50) postoperatively (P < 0.01). There were excelent in 20 knees, good in 11 knees, with an excelent and good rate of 89%. X-ray films showed that hindlimb alignment was apparently corrected, prosthetic position was good, no loosening occurred. These data indicate that total knee arthroplasty, using parapatelar medial approach, obtained good correction outcomes through the accurate amputation to correct hindlimb alignment and selective release of the soft tissue with Legacy posterior stabilized prosthesis in the treatment of valgus knee deformity.

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.
