Objective:Unidentified filling objects (UFO) can cause adverse results including infections, overfilling, asymmetry, foreign body granulomas, dislocation or psychological panic. To remove UFO accurately, it is important to locate and identify the injected substances preoperatively. This study investigated the viability of using MRI to correctly locate and identify injected substances by relating MRI to gross and pathological microscopic examination.Methods:Eighty-two facial UFO patients from 2013 to 2017 were studied by the experts of the Department of Image, Xinhua Hospital of Dalian University. Five of the patients were male and seventy-seven were female. The age ranged from 17 to 58 years with average 29.4 years. They came to our hospital for removal of UFO after they had facial injective fillers in the illegal medial offices. The injected sites involved in the forehead, temple, malar, cheek, nose, nasolabial folds, and chin. All the patients＇ faces were examined with MRI preoperatively, using T1W, T2W and fat-suppressed sequences. Based on the guides of MRI, UFOs were removed with their capsules by open approach. Samples were recorded with digital pictures and then were fixed in 10% formalin solution for microscopic examination of HE stained slices.Results:Based on MRI, gross and microscopic examination, UFO were classified into 3 types, gel-like fillers, solid particles, and growth factors. Gel-like fillers appeared strongly hyperintense on T2 W and STIR sequences and hypointense on T1 W sequences. Grossly, they looked like gruel covered by altered soft tissue. Under the light microscope, many pieces of blue-stained material were dispersed in subcutaneous tissue infiltrated with a large number of mononuclear cells and foreign-body giant cells. Solid particles had low to intermediate signal intensity on T1 W and T2 W images. Grossly, they were like sand merging in soft tissue. The biopsy showed crowed bubbles surrounded by tissue filled with a large number of mononuclear cells and foreign-body giant cells. For growth factors affected tissue, it was hard to differentiate between normal and abnormal on MRI. The affected tissue appeared as somehow hypointense on T1 W sequences and hyperintense on T2 W fat suppressed sequences. During the operation, the affected region was easy bleeding and full of fibrofatty tissue. Under the microscope, there were increased small blood vessels and collagens.Conclusions:Based on MRI, gross and microscopic examination, UFO can be classified into 3 types, gel-like fillers, solid particles, and growth factors. MRI is very important for doctors to assess the patient＇s conditions and make the plan of operation. MRI is also useful for doctors to locate UFO and understand the relationship between UFO and their nearby organs.

OBJECTIVETo discuss the characteristics and reconstruction strategies of acetabular bone deficiency in total hip arthroplasty in order to find the optimal resolution for this clinical puzzle.

METHODSClinical and radiological materials of 37 patients (37 hips) with acetabular deficiency who underwent primary or revision total hip arthroplasty were analyzed retrospectively from May 1998 to August 2008. According to the common classification system for acetabular bone deficiency-the AAOS classification system, the acetabular bone defect was reconstructed using morselized or structural bone grafting, accessory acetabular hardware (ring, cup or cage) together with cemented or cementless acetabular component respectively. All patients were followed up regularly to assess their hip function improvement by measuring the Harris hip score and to find out the grafting bone healing, absorption and position of the prosthesis by plain radiographic examination.

RESULTSThere were 11 primary and 26 revision total hip arthroplasty. There were 9 hips of AAOS-type I defect, 13 of type II and 15 of type III. Morselized bone grafting was used in 24 cases, bulk structural bone grafting in 6 cases and mixed bone grafting in 7 cases. Twenty-one patients used cementless prosthesis and 16 used cemented prosthesis. The average follow-up period was 53.7 months (6.5 to 130.5 months), the average preoperative Harris hip score was 42 +/- 8 with contrast to 87 +/- 5 of post-operation. Statistically significant difference was found according to t-test with P value less than 0.05. Major or complete healing of grafting bone was obtained at the latest follow-up.

CONCLUSIONSAcetabular bone defect during primary or revision total hip arthroplasty should be reconstructed according to its characteristics and severity. For relatively simple AAOS type I and type II cases, morselized or bulk structural bone grafting together with cementless prosthesis could achieve favorable initial stability, but for more severe AAOS type III cases, bulk structural bone grafting with accessory reinforcement hardware would be necessary. Though the early and mid-term results of the above strategies are satisfied, the long term outcome still require further study.

OBJECTIVETo investigate the influence of gender on osteoarthritic knee rehabilitation outcome of osteoarthritis patient undergoing total knee arthroplasty (TKA).

METHODSWe prospectively studied thirty male and thirty female knee primary osteoarthritis patients receiving unilateral TKA with posterior stable-fixed plateau prosthesis at our hospital from March 2003 to March 2008. The age and body mass index of male and female patients were matched. The surgical and rehabilitation clinical factors were compared between two groups.

RESULTSThere was no significant difference in postoperative hospitalization time, surgical tourniquet time, and wound drainage volume between two groups (P>0.05). The extension/flexion degrees of knee joint before operation, 1-week, 2-week and 1-year after operation for male patients were 6.0 +/- 3.3 degrees/114.0 +/- 10.0 degrees, 2.0 +/- 1.6 degrees/93.0 +/- 7.4 degrees, 0.6 +/- 0.6 degrees/104.0 +/- 9.9 degrees and 0.3 +/- 0.5 degrees/125.0 +/- 8.8 degrees, for female patients were 7.0 +/- 3.4 degrees/112.0 +/- 14.0 degrees, 2.0 +/- 1.3 degrees/89.0 +/- 10.9 degrees, 0.9 +/- 0.8 degrees/101.0 +/- 11.8 degrees, 0.4 +/- 0.5 degrees/124.0 +/- 7.1 degrees. The range of motion before operation, 1-week, 2-week, and 1-year after operation for male patients was 108.0 +/- 9.5 degrees, 91.0 +/- 7.1 degrees, 103.0 +/- 9.9 degrees, and 125.0 +/- 8.9 degrees, for female patients was 105.0 +/- 14.1 degrees, 87.0 +/- 11.4 degrees, 100.0 +/- 11.9 degrees, and 124.0 +/- 7.0 degrees. The preoperative and 1-year postoperative HSS scores were 55.8 +/- 13.3 and 89.6 +/- 6.7 for males and 54.5 +/- 13.8 and 89.2 +/- 4.1 for females. No significant statistical difference was observed between two gender groups in regards to degree of extension and flexion, range of motion and HSS score (P>0.05).

CONCLUSIONSGender does not influence postoperative knee function of osteoarthritis patients. TKA significantly improves knee joint function and relieve osteoarthritis-related pain.

OBJECTIVETo evaluate the effect of the early use of recombinant human erythropoietin (rhu-EPO) on neurobehavioral development in preterm infants.

METHODSForty-four preterm infants (30 males and 14 females) were randomly divided into two groups: Rhu-EPO treatment and untreated control (n=22 each). From postnatal day 7, the Rhu-EPO treatment group received intravenous rhu-EPO (250 IU/kg3 times weekly) for 4 weeks. A Neonatal Behavioral Neurological Assessment (NBNA) was performed at 40 weeks of corrected gestational age. A Gesell Development Schedule was used to evaluate neurological development 6 and 12 months after birth.

RESULTSThe NBNA score in the rhu-EPO treatment group (36.20+/-0.75) was significantly higher than that in the control group (34.40+/-1.05) at 40 weeks of corrected gestational age (P<0.05). The developmental quotient of fine motor in the rhu-EPO treatment group was significantly higher than that in the control group 6 months after birth (P<0.05). By 12 months after birth, the developmental quotient of gross motor, fine motor and language in the rhu-EPO treatment group was significantly higher than that in the control group (P<0.05).

CONCLUSIONSEarly use of Rhu-EPO can promote neurobehavioral development in preterm infants.

BACKGROUNDRoux-en-Y gastric bypass (GBP) is the main surgical procedure used in type 2 diabetes. The objective of this study was to evaluate the different types of GBP in treatment of type 2 diabetes.

METHODSPatients with type 2 diabetes were randomly divided into two groups: those who underwent gastrojejunal loop anastomosis bypass and those who underwent gastrojejunal Roux-en-Y bypass. Blood glucose alterations, operation time, and operation complications were observed.

RESULTSGastrojejunal loop anastomosis bypass and gastrojejunal Roux-en-Y bypass were both effective in the treatment of selected patients with type 2 diabetes. Compared with gastrojejunal Roux-en-Y bypass, gastrojejunal loop anastomosis bypass had the advantages of easier implementation, shorter operation time, and fewer operation complications.

CONCLUSIONSGastrojejunal loop anastomosis is effective in treatment of type 2 diabetes. It is safe, easy to implement, and worthy of clinical popularization.

Objective To propose a new evaluation system and evaluate the application value of diabetic retinopathy ( DR) intelligence assisted diagnostic technology based on fundus photography. Methods By using the diagnostic test method,an evaluation system of DR intelligent diagnostic technology based on fundus photography was established. The fundus photographs of 331 diabetic patients (662 eyes) with DR screening were collected in the First Affiliated Hospital of Huzhou University from January 2017 to October 2018. The results of experts ' diagnosis and intelligence assisted diagnosis were compared and evaluated. The evaluation system includes primary evaluation, intermediate evaluation and advanced evaluation. The primary evaluation is the consistency of non-DR ( NDR) in all diabetic patients receiving DR-assisted diagnostic techniques;the intermediate evaluation is the diagnosis consistency of DR lesion degree in patients diagnosed with DR (grade 1-4);the advanced evaluation is the diagnosis consistency of DR classification ( grade 0 -4 ) in all diabetic patients receiving DR-assisted diagnostic techniques. The intermediate evaluation includes two evaluation methods. The main evaluation indicators include sensitivity,specificity and Kappa value. Results Based on experts ' diagnosis, NDR accounted for 22. 7％;mild non-proliferative DR (NPDR),moderate NPDR,and severe NPDR accounted for 19. 9％,18. 7％ and 25. 7％,respectively;proliferative DR( PDR) accounted for 13. 0％. Based on intelligence diagnostic system,NDR accounted for 25. 8％;mild NPDR, moderate NPDR and severe NPDR accounted for 19. 7％,19. 3％ and 22. 8％,respectively;proliferative DR( PDR) accounted for 12. 4％. Based on evaluation system in the paper,the sensitivity,specificity and Kappa value in primary evaluation were 91. 4％, 84. 7％ and 0. 72;the sensitivity, specificity and Kappa value in intermediate evaluation method one were 88. 4％,91. 1％ and 0. 79;the sensitivity, specificity and Kappa value in intermediate evaluation method two were 80. 5％,93. 3％ and 0. 75;the Kappa value in advanced evaluation was 0. 62. Conclusions The evaluation system can be applied to the evaluation of DR intelligent diagnostic technology,and the evaluation result can be used as the basis for the selection of DR intelligent diagnosis application scene.
