Objective To study the relation between the pressure in forefoot and the second metatarsalgia in hallux valgus deformity, finally to quantitatively analyze the pressure under the second metatarsal head which is a dangerous factor leading to second metatarsalgia. Methods Three groups volunteered for this study by a self-devised foot pressure measurement system: fifty-eight normal subjects (116 feet) without pain and deformity in foot, thirty-two patients (45 feet) with hallux valgus and pain only under the second metatarsal head, fifty-six patients (102 feet) with hallux valgus without symptoms of metatarsalgia. The percentage of pressure to weight was the criteria for data analysis. First the pressures under second metatarsal head among three groups were compared with each other. Secondly we used case-control study to identify whether it was high pressure that was likely to result in metatarsalgia. Finally we compared the pressure interval under second metatarsal head among three groups to define the pressure interval which might be a dangerous factor to second metatarsalgia. Results 1)The pressure beneath the second meatatarsal head in patients with metatarsalgia was the highest in the three groups (P

Objective To investigate the clinical efficacy of treatment for chronic pancreatitis and mass in the head of the pancreas.Methods The clinical data of 19 patients with chronic pancreatitis with mass in the head of the pancreas who were admitted to the China-Japan Union Hospital of Jilin University from May 2008 to May 2013 were retrospectively analyzed,including 2 patients with gallstone.Methods of treatment were selected by in traoperative pathological results.All the patients were followed up by outpatient examination and telephone interview till January 2014.Results The operations of the 19 patients were successfully done,including 11 with pancreaticoduodenectomy,5 with exploratory laparotomy and 3 with the laparoscopic cholecystectomy and choledochojejunostomy.The operation time and intraoperative blood loss were (249± 140)minutes (50-390 minutes) and (320 ± 260)mL (50-900 mL).The postoperative mean time of recovery of gastrointestinal function and duration of postoperative hospital stay were 3.0 days (2.0-6.0 days) and 22.6 days (8.0-30.0 days) after the operation.The mean casein-IgG4 of 12 patients was higher (2.64 g/L) after operation.Five patients with operation-related complication were cured after symptomatic treatment,among 2 patients with leakage of the pancreatic fluid,2 with operative incision fat necrosis and liquefaction and 1 with bile leakage.No patients died perioperatively.Nineteen patients were followed up for 11.0 months to 36.0 months with the median time of 28.2 months.The pancreatic head mass of 8 patients with non-pancreaticoduodenectomy were reduced or disappeared by a computed tomography (CT) or magnetic resonance imaging (MRI) rescan,who were treated by the oral prednisone.No complications were detected in the other 11 patients with pancreaticoduodenectomy.Conclusion Method of surgery or medicine treatment for atypical mass in the head of the pancreas is selected according to the pathology results by effective communication with patients and family members,exploratory laparotomy and interpretative aspiration biopsy.

Objective: To study the protective effect of vitamin E in preventing contrast-induced nephropathy (CIN) in patient with coronary artery disease (CAD) after percutaneous coronary intervention (PCI).
Methods: We prospectively studied 206 CAD patients with elective PCI in our hospital and divided them in 2 groups: Treatment group, the patients received oral vitamin E combining vinous hydration,n=102 and Control group, the patients received vinous hydration only,n=104. CIN was deifned by at 48h after contrast media injection, serum cretinin increased up to 25% from the baseline, or reached 44.2 μmol/L. Excluding the other kidney injury factors, the renal functions at 48 h before and after PCI were compared, the occurrence rate of CIN were also compared between 2 groups.
Results:①Overall, there were 19/206 (9.22%) patients suffered from CIN, the occurrence rate in Treatment group (4.90%) was lower than Control group (13.46%), χ2=4.506,P=0.034. For patients with hypertension, diabetes, chronic kidney disease, anemia and mehran risk score<10, the occurrence rate of CIN in Treatment group was lower than Control group,P<0.05.②Compared with pre-operative condition, at 48 h post-operation,Control group showed increased serum creatinine (Scr), blood urea nitrogen (Bun) and decreased creatinine clearance rate (Ccr), allP<0.05.③At 48 h post-operation, compared with Control group, Treatment group presented decreased Scr (86.72 ± 17.73) μmol/L vs (95.13 ± 21.67) μmol/L and increased Ccr (96.75 ± 27.23) ml/min vs (90.70 ± 17.85) ml/min, allP<0.05.④Multivariate regression analysis revealed that elder than 75 years of age (OR=7.278, 95% CI 5.158-11.480), diabetes (OR=3.919, 95% CI 1.330-8.200), chronic kidney disease (OR=6.325, 95% CI 2.137-16.816) and mehran risk score>10 (OR= 4.461, 95% CI 1.589-14.724) were the independent risk factors for CIN occurrence, allP<0.05.
Conclusion: Short-term application of vitamin E may reduce the risk of CIN occurrence at certain degree in CAD patients after PCI.
