  • Effect of Early Enteral Nutrition on the Immune Status of Patients in Intensive Care Unit: A Prospective Control Study

    ObjectiveTo explore the effect of early enteral nutrition (EEN) on immune status of patients in intenseive care unit (ICU). MethodsA prospective control study was conducted from July 2011 to December 2012, and 80 patients after trauma and surgery were admitted to ICU. The Patients were divided into EEN group and normal enteral nutrition (NEN) group randomly. Enteral nutrition in EEN group began within 24 hours after admitted to ICU, while within 48 hours in NEN group. ResultsIn 80 patients, 78(37 in EEN group and 41 in NEN group) completed the end point. The baseline in two groups was consistent (P>0.05). The indicators of lymphocyte, IgA, IgG, IgM and CD4+, CD8+, natural kill cell and pre-albumin values in EEN group were higher than those in NEN group (P<0.05). The incidence of diarrhea (8.1%, 26.8%) and infection of wound (2.7%, 17.1%) in EEN were less than those in NEN group. The hospitalization duration in ICU in EEN group[(7.94±3.72) days] was also shorter than that in NEN group[(10.62±3.14) days]. ConclusionEarly enteral nutrition improves immune function and nutrition status in ICU patients; it also protects gut barrier function and reduces the ICU hospitalization duration.

  • Diagnosis and Treatment of 40 Cases of Pancreatic Cystic Neoplasms

    ObjectiveTo investigate the diagnosis and treatment of pancreatic cystic neoplasm. MethodsThe clinical data of 40 cases of pancreatic cystic neoplasm from October 2001 to October 2013 in our hospital were retrospec-tively analyzed. ResultsPatients with pancreatic cystic neoplasm had no specific clinical feature. Ultrasonography and computed tomography displayed a cystic tumor in 57.5%(23/40) and 72.5%(29/40) of all patients, respectively, but could not distinguish the histological types. All of the patients had been operated, among them 2 cases were misdia-gnosed as pseudocysts and internal drainage; another 38 patients were undergoing the distal pancreatectomy. Pathologic examination results after operation showed 23 cases of serous cystadenoma, 9 cases of mucinous cystadenoma, 3 cases of intraductal papillary mucinous adenoma, and 5 cases of mutinous cystadenocarcinoma. Thirty five patients were followed-up. The followed-up time range from 2 months to 8 years, verage(74.2±12.8) months. Among the 3 patients with mucinous cystadenocarcinoma, 1 patient alived with no evidence of recurrence, the other 2 patients died of tumor invasion and metastasis in 4 months and 7months after operation. The others were still alive now with no evidence of recurrence. ConclusionSurgical resection is the most effective treatment for pancreatic cystic tumor, even if the patients with no any symptoms.

  • Analysis of the Basic Stress Pathway Above Acetabular Dome

    The basic stress pathway above the acetabular dome is important for the maintenance of implant stability in acetabular reconstruction of total hip arthroplasty (THA). The purpose of this study was to describe the basic stress pathway to provide evidence for clinical acetabular reconstruction guidance of THA. A subject-specific finite element (FE) model was developed from CT data to generate 3 normal hip models and a convergence study was conducted to determine the number of pelvic trabecular bone material properties using 5 material assignment plans. In addition, in the range of 0 to 20 mm above the acetabular dome, the models were sectioned and the stress pathway was defined as two parts, i.e. 3D trabecular bone stress distribution and quantified cortical bone stress level. The results showed that using 100 materials to define the material property of pelvic trabecular bone could assure both the accuracy and efficiency of the FE model. Under the same body weight condition, the 3D trabecular bone stress distributions above the acetabular dome were consistent, and especially the quantified cortical bone stress levels were all above 20 MPa and showed no statistically significant difference (P>0.05). Therefore, defining the basic stress pathway above the acetabular dome under certain body weight condition contributes to design accurate preoperative plan for acetabular reconstruction, thus helping restore the normal hip biomechanics and preserve the stability of the implants.

  • EFFECTIVENESS OF SLIDING OSTEOTOMY FOR CORRECTING SEVERE VALGUS DEFORMITY IN TOTAL KNEE ARTHROPLASTY

    ObjectiveTo explore the surgical technique and effectiveness of sliding osteotomy of medial femur condyle in handling soft tissue balance of severe valgus deformity in total knee arthroplasty (TKA). MethodsBetween June 2008 and February 2014, 18 cases (19 knees) of severe valgus knees undergoing sliding osteotomy of medial femur condyle in primary TKA were included. Of the 18 patients, 6 were male and 12 were female with an average age of 52.3 years (range, 29-72 years), including 3 cases (3 knees) of osteoarthritis, 11 cases (12 knees) of rheumatoid arthritis, 3 cases (3 knees) of post-traumatic arthritis, and 1 case (1 knee) of deformities in skeletal dysplasia. Before surgery, the tibial-femur angle (TFA) was (33.0±2.9)°; the Hospital for Special Surgery (HSS) score was 41.6±7.7; the Knee Society Score (KSS) lateral stability score was 6.0±5.4. All cases were rated as type II according to Krackow classification of valgus knee. During primary TKA, sliding osteotomy of medial femur condyle was performed via a medial parapatellar approach. ResultsIncision healed by first intention in all cases. Peroneal nerve palsy occurred in 1 patient, which was cured after 6 months of conservative treatment. Eighteen cases were followed up 19 months to 7 years, with an average of 5.7 years. All patients had no complications of deep vein thrombosis, deep infection, and prosthesis loosening. X-ray films showed that bone healing was achieved in all cases at 6 months. At last follow-up, the TFA was (4.8±1.8)°, showing significant difference when compared with preoperative value (t=62.61, P=0.00). The HSS score was 87.2±10.5 and the KSS lateral stability score was 12.4±3.1, all showing significant differences when compared with preoperative scores (t= —33.35, P=0.00; t= —6.83, P=0.00). ConclusionSliding osteotomy of medial femur condyle is effective for correcting severe valgus knee deformity during TKA. Satisfactory joint function and stability may be achieved.
