Background Sugar cataract is one of the major diabetic complications in the eye,but there is not effective medicine to prevent or delay development of cataract. Objective The goal of this study was to investigate the effects and the potential mechanism of aldose reductase (AR) inhibitor,AL-1576 on prevention of galactose cataract in rats. Methods Forty-two SD rats were randomly and equally divided into 7 groups.The cataracts were induced by feeding with 50％ galactose.At the day of feeding galactose and the day 5,10 and 15 after feeding galactose,AL-1576 was added into the feeds.The rats were divided AL-1576 prevention group and early-,intermediate-or late-stage intervention groups.For another group,the withdrawing AL-1576 group,AL-1576 was added into the feeds at the day of feeding galactose,then was removed after 10 days.The lenses of the rats were examined under the slit-lamp microscope before and after given AL-1576 every 5 days.At the day 35,the lenses were obtained.The wet and dry weight of the lenses were weighted,respectically,to calculate the water content of the lenses.Activities of AR and superoxidedismutase (SOD) and contents of glutathione (GSH) of the lenses were measured by their commercial detecting kits.The care and use of the animals complied with the Regulations for the Administration of Affairs Concerning Experimental Animals by State Science and Technology Commission. Results In AL-1576 prevention group,all lenses maintained clear.Opacification of the lenses were significantly attenuated in all three AL-1576 intervention groups and withdrawing AL-1576 group compared with the cataractous model group ( P＜0.05),but the inhibiting role was weaken with late intervention.The water contents and the activities of AR of the lenses were decreased,the contents of SOD and GSH were dramatically increased in all different AL-1576 treated groups compared with the cataractous model group (P＜0.05).Moreover,AL-1576 prevention group showed the best effect on all indexes (P＜0.05). Conclusions The activity of AR can be inhibited by AL-1576 at the different stages of development of cataract induced by galactose.By blocking and attenuating formation of the edema and elevating antioxdative capacity in the lenses,AL-1576 prevents and delays the formation of galactose cataract.

Objective To observe the clinical effectiveness of alprostadil combined to pancreatic kininogenas in the treatment of gerontal diabetic peripheral neuropathy.Methods Totally 90 gerontal patients with diabetic peripheral neuropathy were randomly divided into three groups,the first group received the treatment of mecobalamin,the second group received mecobalamin plus pancreatic kininogenas,the last group received mecobalamin,alprostadil and pancreatic kininogenas (30 cases for each).The course of treatment was 4 weeks,the nerve conduction and effective rate of 3 groups were compared after treatment.Results Compared with the first group(53.3％),the total effective rate was significantly improved in the second group (80.0％)and the third group(100.0％) (P＜0.05).After treatment,the therapeutic effect of every group was boosted,and the second group was better than the first group,and the last group was best(P＜0.05).Conclusions Alprostadil combined to pancreatic kininogenas is effective and safe for the treatment of elderly diabetic peripheral neuropathy.

Objective To study the risk factors of aortic arch calcification (AoAC) in maintenance hemodialysis (MHD) patients.Methods Retrospective analysis was performed in patients who accepted MHD ≥ 5 years.The clinical data were collected.The images of plan chest radiograph detected during followup period were reviewed by certain imaging physicians,and the AoAC score was calculated.Logistic regression model analysis was proceeded to study the risk factors of AoAC.The patients were divided into AoAC positive group (29 cases) and AoAC negative group (37 cases) respectively.The clinical parameters were compared between the 2 groups.Results Sixty-six patients (21 male,45 female) were selected.The year AoAC scores from the zeroth to fifth year were (0.013 40 ± 0.074 96),(0.018 90 ± 0.078 55),(0.118 50 ± 0.170 06),(0.157 00 ± 0.207 55),(0.166 00 ± 0.205 37),(0.175 50 ± 0.222 29) scores,progressively.There were significant differences in AoAC score from the third year compared with that of the zeroth year (Z =-3.984,-4.021,-4.017;P ＜ 0.01).Logistic regression model analysis result showed that only the age of dialysis beginning was the risk factor for AoAC (relative risk 1.177,regression coefficient 0.163,P =0.002).The age of dialysis beginning,rate of diabetic nephropathy,serum calcium-phosphate product were significantly higher in AoAC positive group than that in AoAC negative group [(59.5 ± 12.6) years vs.(52.9 ± 13.2) years,27.6％(8/29) vs.2.7％(1/37),(5.81 ± 1.63) mmol2/L2 vs.(4.13 ± 0.86) mmol2/L2].Conclusions The AoAC will aggravate with the increased duration of dialysis in MHD patients.The age of dialysis beginning is the risk factor of AoAC.

Objective: To investigate the risk factors for mortality in neonates with congenital esophageal atresia (CEA) and simple congenital heart disease (CHD) including atrial septal defect (ASD), ventricular septal defect (VSD) and patent ductus arteriosus (PDA). Methods The medical records of neonates with CEA and simple CHD who had surgery in Children’s Hospital of Chongqing Medical University from 1998 to 2013, were analyzed retrospectively. Factors including neonatal demographics, laboratory results and complications after surgery were compared between survivor and non-survivor groups. Results Seventy ifve cases were included in this study and the mortality was 10.67%(8/75). There was no signiifcant difference between non-survivor group (n=8) and survivor group (n=67) in factors such as gestational age, birth weight, age of admission, age at surgery, duration of surgery, full blood examination, serum electrolytes, blood gases, prevalence of septicemia, pneumothorax, and cold lesion syndrome. However, the prevalence of respiratory failure and heart failure in non-survivor group was higher than that in survivor group (75%vs. 9%, P=0.000;50%vs. 1.5%, P=0.000, respectively). Conclusions The poor outcome among neonates with CEA plus simple CHD might be associated with respiratory failure and heart failure.

Objective To investigate the clinical results of resection of periacetabular tumors and reconstruction with fibular autograft. Methods Eight patients with tumors around acetabular were treated surgically in Tongji Hospital between January 1999 and April 2003. The series comprised 5 males and 3 females, with an average age of 39.6 years old (range, 21-65 years old). One patient was diagnosed with osteosarcoma, 2 with chondrosarcoma, 3 with metastatic bone tumor, 1 with giant cell tumor(GCT), and 1 with aneurysmoid bone cyst. There were ⅠB in one patient, ⅡB in 3 patients according to Enneking surgical staging in four primary malignant tumors patients. The tumors involved the zones Ⅱ of Enneking classification in 5 patients, the zonesⅠand Ⅱin 3 patients. All the 8 patients with periacetabular tumors underwent resection and reconstruction with fibular autograft(including 3 cases of a free vascularized fibular graft). Functional results were evaluated according to the system of the Musculoskeletal Tumor Society. Results Bony union occurred 15.2 weeks (range 14-16 weeks) in 5 patients reconstructed with non-vascularized fibular graft and 13.6 weeks (range 12-15 weeks) in 3 patients reconstructed with vascularized fibular graft after the initial surgery. Five of them were followed up ranged from 14 to 42 months (mean 28 months). There were continuously disease-free without complications during follow-up. At the final followup, the average functional score was 22 (range 18-27) according to the system of the Musculoskeletal Tumor Society. The good and excellent rate of functional results was 100%. Conclusion Tumor resection and reconstruction by fibular autograft is an effective treatment for patients with periacetabular tumors. Satisfactory postoperative function was obtained, and relief of pain and walking independently could be achieved with a high level of patient satisfaction.

[Objective]To introduce the new concept of "terrible triad of the elbow",and report the preliminary results of 5 clinical cases.[Method]From April 2004 to March 2007,five cases met the diagnosis of terrible triad,with posterior dislocation of elbow complicated with radial head and ulnar coronoid fractures.The radial head fractures were 4 in type Ⅱ and I in type Ⅲ according to Mason classification,and Ⅰ in type Ⅰ,Ⅲ in type Ⅱ and 1 in type Ⅲ according to Schatzker classification.The ulnar coronoid fractures were Ⅰ in type Ⅰ,Ⅳ in type Ⅱ according to Regan-Morrey classification,and all 5 in type Ⅰ according to O'Driscoll classification.Four patients underwent surgical operations.The fractured radial head and ulnar coronoid were reduced and fixed with 3mm titanic lag screws or K wires,the lateral and medial collateral ligaments were repaired with Krachow sutures.A plaster of Paris was applied for 3 weeks after operation,in position with elbow flexion in 90 degrees and forearm rotation in neutral.Then physical exercise and rehabilitation program were carried out.[Result]Four operated patients were followed up for 3 months to 3 years,with healed fractures,stable elbow and no pain movement.The average range of elbow flexion-extension were 120 degrees,and forearm pronationsupination were 110 degrees,respectively.The functional outcome in 3 cases that followed up more than Ⅰ year was excellent in 2 and good in Ⅰ according to Mayo Elbow Performance Score(MEPS).The result of the un-operated case was poor in MEPS evaluation.Elbow instability and pain was the main complaint.[Conclusion]Terrible triad of posterior dislocation with radial head and ulnar coronoid fractures is a severe trauma to the elbow.Operative osteosythesis and ligament repair is mandatory for concentric reduction and elbow stability.
